LIGHT STEEL FRAME (LFS) LIKE MANY MODERN METHODS OF CONSTRUCTION IS BECOMING LESS OF A NICHE MARKET AND A REAL GROWTH AREA WITHIN THE CONSTRUCTION SECTOR. MODERN ENGINEERED SOFTWARE SOLUTIONS WAS STARTED TO FILL A VOID IN THE MARKETPLACE FOR ENGINEERS WANTING TO DESIGN IN LIGHT STEEL FRAME.
The add in for Tekla Tedds enhances LSF capabilities within the existing portfolio and improves the easy-to-use structural analysis software. The add in is available as a standalone version with all manufacturers data available or as a bespoke version tailored to each company.
Users enter data such as span, joist centres and loads applied, then select profiles from over thirty manufacturers.
Over the years more features have been added - the software now includes:
• Pitched Roofs in LSF using the 2D Analysis engine built into Tedds
• Members are rotatable on plan - for roofs, C section joists and lattice trusses
• Floors, roofs and trimmers (single members) can be pitched up to 90o
• Studs as part of a wall system or a single stud
• Lintels can be designed as lattices or compound C sections in load-bearing walls
• Facade designs comply with ED019 and FIS guidance
• Racking, sliding and overturning of building
• Offers weight per square metre or linear metre as appropriate for pricing
• Provides all that is needed to design multi-storey buildings in hours
Users can switch within calculations between British and European Standards enabling rapid comparison of results. The latest software provides calculations to both British Standards (BS 5950-5) and Euro Codes (EN1991-1-3). Given that wind is one of the critical design factors for roofs and walls, a bespoke version of Breve that links to the existing Tekla Tedds wind modules for BS 6399-2 and EN1991-1-4:2005+A1:2010 has been developed. The software uses the Nasa Topographical database in Breve to populate the site-specific details for wind analysis to the nearest one hundred metres, as opposed to the nearest town as the standard data contained in Tedds.
Included with the latest version of the software is bespoke fire rating calculation based on test data and design loads as well as duo-pitched roofs and self-weight of all members. Future updates include multi-span beams for joists and trimmers and improved lintel options. On average an update is issued every two months. Working with Vertex UK a two-way link between Vertex and Tedds has also been developed using the built in Excel export and import tools. It means that users can fill in one form in Tedds and within thirty minutes be rolling metal to assemble into a bespoke two-storey house.
In addition, Modern Engineered Software Solutions in partnership with sister company MMCEngineer, are now offering monthly training sessions on the design of light steel frame using the add in, as well as producing research with a number of universities, including Northumbria and Leeds Universities.
