New Tekla Structural Designer update features bidirectional link to Fabsec software

Building under construction using long span cellular beams

A new partnership between Trimble and Fabsec in the UK sees the launch of a bidirectional link between Trimble’s latest Tekla Structural Designer (TSD) 2020 update and Fabsec FBEAM® software.

The link means data can flow freely between the two packages, saving design time and ensuring the most efficient project solution is achieved.

Structural and consulting engineers, as well as D&B fabricators of steel-framed buildings, are able to download the free FBEAM® software from the Fabsec website, and design long span cellular beams to the Eurocode.

Typically used for primary and secondary floor beams on multi-storey projects, applications include composite and non-composite plain or cellular beam construction with floor spans of 8-24 metres.

Offering enhanced architectural freedom, and particularly suitable for irregular shaped openings, the software allows maximum flexibility of web service penetration including circles, rectangles and elongated shapes in whatever position required.

Rather than selecting an off-the-shelf solution, an engineer is able to create a design that offers the optimum beam with any beam depth, flange width or web/flange thicknesses (including asymmetric beams); creating lighter beams that can also offer cost savings.

Providing a more accurate and efficient process, the Tekla Structural Designer 2020 bidirectional link allows the user to pull one, or hundreds, of Fabsec beams in to the FBEAM® software for design and loading. This new, time saving approach eliminates the need to design each beam in isolation, avoiding manual data input as well as the risk of human error.

Commenting on the partnership that has made this happen, Sharon Green, Fabsec Business Development Manager said: Fabsec started in 2001 and since then FBEAM® has established itself as the industry’s leading software solution for the design of plated cellular beams in ambient and fire conditions.

With a track record of continuous development, to ensure FBEAM® remains at the forefront of engineers’ needs, we are pleased to announce our recent partnership with Trimble to develop this import/export regime between FBEAM® and Tekla Structural Designer. This latest update allows a seamless transfer of data between the two software packages making the design and specification of FBEAM® plate girders even more streamlined.

This new feature will help structural engineers to improve their workflows, allowing any number of options to be reviewed effortlessly with the additional benefit of the ambient design properties being synchronised to optimise the fire design within FBEAM®.


Fabsec software is only compatible with the latest Tekla Structural Designer 2020 release and can be downloaded in the UK from the company’s website
