This building, with 3 storeys below and 44 above the ground is located in Gwangju, Korea and is designed with RC (Reinforced Concrete) and Steel structure.
Since steel structure is vulnerable to heat, the student project team used slab system for fire-resistant structure. They applied diagonal grid to reinforce building’s resistance and kept applying it to entire structure to ensure extra spaces by reducing the number of pillars. The structure system is made up of triangle shape of vertical member and beam conveys safely to the base and the ground by dividing the vertical load properly. Also, using the similar mechanism to strut tie, it can resist an external force. And it will be located at the outermost of the building, effectively corresponding to horizontal load such as the earthquake and the strong wind. By applying the two core systems, the students designed for it to be able to resist the transverse load. There will be higher effectiveness of the space by applying the two core systems, also they can expect effectiveness of constructability and construction cost reduction. Since the base part needs big bearing power according to the characteristic of the skyscraper, the students have chosen to use mat foundation and Roller Compacted Dam-concrete method (RCD method), so that it is designed in a way that it can relatively get huge support capacity. They also improved the resistance performance by applying the Outrigger Belt Truss System which effectively resists to a wind load and an earthquake load.
Problems Faced & Solution
Size of the project got too big because the number of objects increased when the project team was connecting each part of steel-frame structure. It caused computer to slow down and decreased work efficiency. To solve this issue, they used Phase function of Tekla Structures. With that, they split the project into several parts to speed up their work and combine them together. It saved a lot of time and bumped up work efficiency.
Benefits of using BIM and Tekla for the project
This project’s main material was RC and Steel. There is no program other than Tekla that can do RC and Steel modeling at the same time and that can apply the detail connection and various types of the technologies. The students connected it easily by component which was provided basically when they were doing the modelling. Since it was easier to change the setting of the visibility of the member of framework than the other programs, it helped the team a lot in their understanding of true teamwork and presentation.
Last but not least, this student team from Chosun University commented about Tekla Structures' visibility being one of the best among software that is currently available on the market. With Tekla Structures’ strong visualization function, the students could understand and manage the project a lot better and it helped them produce presentation and improved collaboration.
