钢结构模型 - Tekla

Advanced Candu Reactor, Canada

Atomic Energy of Canada Limited

Comprehensive concrete module
The term module can be defined as an assembly comprised of structural steel, pipe supports, process piping & equipment, instrumentation, cable trays, panels, embedments, rebar, etc. within a defined volume. Models can be prefabricated either off-site or at an on-site fabrication facility and installed in the field. Constructing with the module concept allows fabrication of many modules to take place as parallel activities, shortening the overall construction schedule while fabricating in a controlled environment. This particular example represents a Prefabricated Permanent Formwork (PPF) Multi-Discipline Module. Which translates to a module consisting of process piping & equipment, steel wall plates, embedments, temporary steel, rebar, etc. The plate work that makes up the walls act as the formwork and remains in place after the concrete has cured.

Passing on the model downstream
This project is still in the preliminary stage and has not passed anything out for fabrication yet. However, AECL is working closely with fabricators/detailers to develop standards that will be used to build on when information starts to flow between all parties. The BIM process will allow AECL to pass a 3D model from their design team to contractors, detailers, fabricators, etc. each adding their own additional details to the original design model. The result should greatly increase the quality of the model and reduce the information loss when the model is passed between disciplines.

ALDAR HQ, Middle East

William Hare

Middle East's first spherical building
ALDAR's new headquarters is the first spherical building in the Middle East, standing approximately 110m in height with 23 floor levels. The building has a diameter of 120.9m; its width varies from 10m at ends to 36.4m in the middle. The structural design has a central concrete core for transferring environmental lateral loads with peripheral diagrid support columns forming the building’s envelope. The building requires 6400 ton of steel; 55,000m2 of decking panels, and 25,000m3 of concrete and has an area of glass of 25,000m2 (3200 panels of glass). The building will have a total gross floor area of 61,900m2 and a total net area of 51,361m2.The building includes many complicated elements, such as peripheral diagrid columns, outer ring, internal ring, central ring columns, diagrid nodes, and in plane truss connecting the outer, internal and central columns at all floor levels. The roof is an integral part having primary beams in line with the columns.

Engineering and model data used at the earliest stages
William Hare Engineering utilizes computer aided design and detailing using Tekla software to develop client’s designs, maximize efficiency and to engineer practical solutions for its manufacturing facilities. Engineering and model data were used at the earliest stages of the project to take full advantage of early procurement and optimized material utilization. In engineering a time saving of 5% is achieved while utilizing the architect’s or consultant’s model with no increase in accuracy. If they would have had to use 2D information on follow-on trades, it would have added another 20% to the detailing of the project. In the fabrication the Tekla drawing details were used seamlessly with in-house fabrication data package, such as for producing NC files for use with CNC machines and bill of material data manipulation. During erection the drawings and reports along with the Tekla Web Viewer models were utilized for more accurateness.

Artwork Sirocco, Finland

A-Insinöörit Suunnittelu Oy

430 aluminum profiles
Sirocco is work of art located in the Arabianranta housing area in Helsinki. It was designed by Kivi Sotamaa of Sotamaa Design and consists of 430 aluminum profiles, the length of which varies from 1,15 to 4,45 meters. All connections were modeled by using Tekla Structures’s custom components. The lower end of the artwork is connected to pad footings, and its profiles are supported by plywood plates during the construction phase.

Direct data transfer from the model to analysis and fabrication
Finnish engineering office A-Insinöörit Suunnittelu Oy used Tekla Structures version 15.0 for the structural design of the project. Architect design was done by Maya Unlimited and Rhinceros 4.0, and that information was exported to Tekla Structures in 3D DWG format. The places of profiles were delivered to measuring devices directly from Tekla Structures. The data for the plywood supports and aluminum profiles were exported from the Tekla model directly to CNC-machines.

Capital Gate, Middle East

Eversendai

World’s most inclined building
Capital Gate is a 35-storey illustrious iconic tower, 525 feet tall, a part of the Capital Center development around Abu Dhabi National Exhibition Center. It features a presidential-style luxury hotel and office spaces. Leaning towards one direction in an angle of about 18 degrees, the tower has been nominated for the Guinness Book of World Records as the world’s most inclined building. The structure features a cantilevered internal atrium at 17th and 18th floors to accommodate the facilities of the projecting swimming pool and tea lounge. Diagrid technology has been adopted in the construction of the structure. Each diamond of the external cladding is supported by the steel diagrid panel. To maintain the required curved surface profile, every panel surface is slightly deviating with respect to the adjacent panel surfaces. External diagrid members are of rectangular hollow tubes whereas the internal diagrid members are of circular hollow pipes. External diagrid members provide secondary supports for the wave-shape ‘Splash’ structure from 19th level down to the bottom, providing an aesthetic sun shade to the tower. Main structural steel work has consumed more than 13,000 tons of material in addition to the metal decking. Steel skeleton consists of 707 external diagrid nodes and 20 internal diagrid nodes at the intersection of the members. At the intersecting nodal points, the hollow members have met with offsets in all three axes along their surfaces. As none of the panels is coplanar to the other, each node is unique on its own and formed with heavy thick cruciform punchthrough plates. In order to minimize the member offsets at the nodal points, diagrid members are oriented by using the method of ‘bisection of bisecting planes’.

Faster and safer completion by BIM
Complexity in modeling the diagrid members was well managed with the features of Tekla Structures. The Tekla attributes helped in all fronts for a smooth construction of the structure. Concerning design, members were oriented with minimal offset by adopting the method of bisection of bisecting planes. These offset values were taken from the 3D model and used in the design of cruciform nodes. Available length of weld was taken from the model to do the weld design of cruciform nodes. Beams connected to the nodes were moved in the 3D model to avoid member clashing which resulted in eccentric connections. The eccentricity was measured from the model and used in the connection design. From the preliminary model developed at the initial stage of the project actual cut-to-length of the members was taken to procure the material. This helped in reducing material wastage. Quantity of bolts, shear studs and paint was obtained from the Tekla Structures reports. Assembly lists derived from the Tekla model were converted into worksheets. Other departmental activities, like fabrication, painting and erection, were planned and monitored using these worksheets. The NC files exported from the model facilitated faster and accurate fabrication. Temporary jigs were made with the help of the coordinates of individual assemblies that were taken from the model. Fit up of the individual parts of the nodes wasdone with the 3D coordinates taken from the model. Location of center of gravity and weight of individual assembly were taken from the reports. These were used to work out the lifting method statement and in the design of erection engineering. Bolt report based on the assembly mark helped the rigging team to have control over bolt usage. 3D global coordinates taken from the Tekla model were utilized for erecting the diagrid assemblies at their exact position. The 3D model was also given to the cladding team to work out the design of the cladding system. The model was used to coordinate with the architectural profile model to nullify the interface issues. Thus the model generated in Tekla Structures had played a vital role in the successful completion of the works in a safe and faster way.

Carbon boiler plant 11, Germany

Ingenieurbüro Dipl. Ing. Klaus Mayer

Designed completely by BIM

The whole building, including parking area, was modeled in Tekla Structures. In the summer 2009, as the Tekla Germany model competition was ongoing, the plant was still under construction. Materials used in this model are steel and concrete. BIM was utilized in the whole planning and construction process. The boiler plant was designed completely in Tekla Structures, there were no architectural data imported as reference. All the structures were modeled in Tekla Structures. Tekla Structures Web Viewer was used in the project as an over-all communication tool between all project parties.

Castle House Wind Turbines, UK

Bourne Engineering Limited

Sharing the model was critical
The Castle House is a 43-storey residential tower and will stand 147 meters high providing 310 new apartments. This entry is for the wind turbine enclosure that sits on top of the tower. The housing for the turbines is a complex curved structure supporting the cladding system and the turbines themselves which are 9 meters in diameter. Because of the complex nature of the structure, it was critical that the as-built model could be shared with the cladding specialists to ensure there were no problems on site and that Bourne Engineering could take information from the turbine manufacturers to ensure the unique basketry was in the correct positions to ensure a first time fit.

重庆温室植物园,法国 (Chongqing Arboretum Greenhouse, France)

Marchegay

非对称弯曲的隧道
整个植物园是由非对称弯曲隧道组成，每个隧道半径各不相同。中央大厅位于两侧隧道的温室交叉处，由三个不同弧形的从地基中引出的半圆组成。使用铝和玻璃制成的一个全封闭的弧形遮阳系统，其主体结构由镀锌圆管组成，结构用钢量为736吨+58吨的室内墙（不包括接合模型）。

CIDCO Exhibition Center, India

inSTEEL ENGINEERS PVT. LTD.

Preferred venue for green conferences
The Exhibition Center is providing quality exhibition and business facilities in the Mumbai metropolitan region, and would also be the preferred venue for green/eco conferences and a permanent green awareness gallery. All profiles are hollow circular, rectangular or square sections, procured from UK, Japan & Korea, due to high yield strength of material. The required lengths had to be matched as per rolled lengths available, and the material list was preparedaccordingly. After the procurement of the material, the received lengths were compared and matched with the actual lengths as per the fabrication drawings, and the two matched almost perfectly. This resulted in bare minimum wastage and hence cost savings. This fact was highly appreciated by the client. All connections are non-conventional type and were required to be developed and also placed in the model individually.

Managing complex geometry and interoperability
"The main reason for adopting Tekla Structures 3D BIM technology is complex geometry of the said structures having semi parabolic shape, and interoperability was the another major requirement", says Raju Jagtap, Director of inSTEEL ENGINEERS Pvt. Ltd. "We have used the model to interact with structural consultant, civil contractors as well as roofing contractors. The design of roof and structural members likes tubular trusses of MS tubes/boxes is innovative. Tekla Structures is easy to use and available macros help create such a complex geometry in the shortest span of time which leads to save hundreds of man-hours. Another major challenge was modeling facades and roofing elements over these structures. This major requirement has been successfully achieved by using Tekla's best interoperability functionality to get real time full visualisation of the whole structure."

CO naar Stoom, Benelux

NEM

Toxic gas combusted into carbon dioxide
In the beginning of 2008, NEM kicked off the engineering of a CO-boiler for an oil refinery. A fluid catalytic cracker installation for oil is producing high amounts of carbon monoxide. This highly toxic gas both for humanity and environment will be combusted through our installation into carbon dioxide. The CO-boiler is in fact a big heat exchanger (up to 1100°C) to generate steam. Hot gasses are being transferred through the boiler through a circuit of steel water pipes. In this way the heat efficiently converts water into steam. The steam is used to drive a steam generator or is used for other process purposes.

Subcontracting based on the model
A case study has been carried out on the consequences of heavy earthquake loads on the boiler steel support structure. The final calculation model has been used to put up a 3D-layout model within a short period of time. The latest version 15.0 of Tekla Structures proved itself in this; especially the single-click mouse option increased the work speed. The gastight boiler outside casing ensures safe and efficient passing through of the toxic flue gasses. The big round gap is the connection to the burner unit in front of the boiler. Hot flue gasses will pass through the inlet ducting to the boiler internals, the circuit of steam/water pipes. On the rear end the cooled down gasses are disposed to a stack. Different levels of platforms and ladders provide necessary accessibility to the boiler. The steel structure next to the boiler houses the systems to service the boiler internals. Based on this model different parts have been subcontracted for detail engineering and production. This model has also provided visualization of the boiler design development towards the client and has been used for important clash checking within the total plant layout. Great advantage is the possibility to import various types of 3D files without directly overloading a computer.

Darling Downs Power Station, Australia

Steel Fabrications Australia

Comprehensive delivery of composite concrete and steel
This project consisted of the supply, fabrication, and protective coating of 2,300 tons of structural steel and composite flooring systems. There are two main buildings in the contracted works. The first called the CTG Building houses three gas turbines comprising of 900 tons of structural steel. The second is the STG or the steam turbine building consisting of main building structural steel and a series of levels of composite concrete and steel floors throughout. Walkways and access platforms throughout the project have also been supplied by Steel Fabrications Australia. The company also provided all the pipe racks required by the power station for both the transporting of liquefied natural gas and the delivery of steam to the condensation and reclaiming structures.

Phasing of assemblies ensured erectable deliveries
The BIM benefits for this project include importing data from Tekla to FabTrol software (at least a 85-90% time saving for each release of drawings) to obtain doc control and BOM. For production, there was a 50% saving with retrieving of data from FabTrol saving 80% of time when request. Purchase order and tracking saving of 60% with less waste of material via FabTrol optimisation. Tekla Structures was cusyomized to suit the high quality of drawings required by the workshop, which enabled the fabrication to follow through the shop with ease. Phasing the assemblies through Tekla allowed steel to be ordered and fabricated to ensure delivered steel is in an erectable sequence. Important to this project as Steel Fabrication Australia was not the rigging contractor. Clarity of drawings produced from Tekla on complex assemblies ensured accuracy of fabrication.

DBCT 7X OL3 Onshore Including Surge Bin SB3, Australia

Suresteel Detailing

Structural steel, platework surge bin and mechanical items
Construction of the onshore outloading system for the DBCT 7X project at Dalrymple Bay Coal Terminal South of Mackay (Qld). The project involved the construction of three conveyors, L11, L11A & L13, Drive Tower L11/L11A and the surge bin SB3 and sample plant SP3 building plus modifications and upgrades through the existing transfer towers. The model comprises of structural steel, platework surge bin, and mechanical items including head frames, pulleys frames, skirts, guards and some chute components.

BIM collaboration ensured positive project outcome
The DBCT Surge Bin SB3 & Sample Plant SP2 complex was undertaken in 2007/2008 to be modeled using Tekla Structures 12.1 and utilized BIM processes in conjunction with other steel detailers using a different software product (AutoCAD-based 3D system) and equipment suppliers for the project. The information transfer between the other steel detailers worked both ways, with Suresteel Detailing providing them with 3D DWG versions of the model for them to undertake the piping and some other aspects of their scope. Their information was then referenced into the Surge Bin model to ensure there were no clashes and the interfaces all met up correctly. The 3D models were also sent to the drive suppliers to enable them to design the hydraulic piping routes and pipe supports for their installation works on the project. The use of BIM processes and collaboration between parties ensured an effective and positive project outcome.

Estadio Chivas, Mexico

Heimsa

Roof of curved and straight round tubes
This is a roof structure of a new soccer stadium in the city of Guadalajara, for the world famous Chivas soccer team, which also owns a franchise in the United States called Chivas USA. The main members are all curved round tubes, the secondary ones straight round tubes and purlins. The design and the erection sequence were planned around dividing the overall structure in four quadrants, each consisting of three full and two half subdivisions called modules. The two half modules were shared, half each, by two adjacent quadrants. The overall structure is supported by 16 concrete columns. The curved structure itself is 190' wide and 36' deep, the overall structure is about 600' x 900'.

Major savings in shop engineering
Tekla Structures was used to detail the project after a Staad design model was imported, and was also used to create an architectural IFC model that was later incorporated in a Revit architectural model. The unique connections required several custom components to be created to adapt to the many occurrences in the overall project. By using the unique 3D representation in Tekla Structures and the accurate dimensioning tools in drawings one person was able to accomplish the shop engineering in the same period of time it would have taken a team of several people using other detailing methods.

Student entry, Germany

Husein Kurtovic, Aachen University of Applied Sciences, Civil Engineering

Column free jumbo jet hangar
The winner of the first Tekla Germany model competition is an entry of a student of civil engineering at the Aachen University of Applied Sciences. The existing jumbo jet hangar was modeled in Tekla Structures as part of master thesis. Because of the size of the Boeing 747 airplanes, the main requirement for the building was to be built totally column free. Special feature of the building is a double-arch which goes 55m above the building floor and forms the main plane structure. Two trussed beams adjust the horizontal thrust. These together with the orthogonal secondary beams build the support grid of the entire hangar. Three stiffening girder telescoping parallel with the trussed beams strengthen the support grid. Vertical supporting loads of the double-arch have been adjusted by four brackets. Furthermore, vertical load is being given off from the secondary beams to the back wall and from the trussed beams and the stiffening girder to the flank wall. In the hangar model BIM was utilized first of all in the input of the data from an already existing building.

The Fietsappel, Benelux

Iv-Consult

Heavyweight engineering enabled lightweight design
The Fietsappel is a very special kind of bicycle garage in Alphen aan den Rijn in The Netherlands. Approximately 1000 bicycles can be parked in this garage. Its apparently simple basic form (an apple) is somewhat misleading as its three dimensional design is, in fact, highly complex. The ramp on which the bicycles are parked is spiralled like an apple peel around a cone-shaped core of steel columns. The outer shell is made from transparent lace fence. Due to the complex three-dimensional structure of this unique design, not one element is the same. The best material to build this structure with is therefore steel. This lightweight design nevertheless requires a heavyweight engineering approach. Iv-Consult was responsible for the calculations, design, detailed calculations and shop drawings.

Platform maintenanc and well intervention
The transport boat concept has been in use for quite a number of years. These barges are a proven concept and there are a number of them operating around the world showing that they are a cost effective method for platform maintenance and well intervention. The barge is shown as transporting a module to be installed on an FPSO. The barge is also capable of carrying complete drilling equipment with the drill strings for installation on a jacket and performs the drilling with sufficient power and utilities from the barge.

Extensive use of custom components
Lamprell is likely to be the first to use Tekla Structures for fabrication detailing for a barge. They used a number of custom components for creating panels, making cut-outs on bulkheads, preparing pipe sleeves, haunch plates, nodes, etc. Tekla custom components were used to create weld preparations with great ease and generate fabrication sequences. The Tekla model helped in identifying clashes within steel, tertiary, weld accesses, etc. Profiled Bilge Keel plates were successfully modeled and developed for forming in this project.

Prestigious administration building
Yas Island building is Abu Dhabi’s prestigious administration and commercial building project. Tekla BIM technology helped to model the building with ease to achieve ayster shape hard shell roofing wrapping over the building and enclosing the transparent fluid glass facades within. The main challenge was to achieve this building’s complex architectural shape which is carved out to reveal the inner facades, which is reminiscent of Abu Dhabi’s maritime culture of wooden boards with triangular sails. Tekla Structures allowed to model such a great shape with the overhanging roof acting as a canopy, the shell type roofing form the encasing.
