SCI develops New Eurocode version of TSLAB V3.0.
SCI has developed a new version of the TSLAB software design too which facilitates the design of composite floor slabs in fire conditions, using the design method described in SCI publication P288 Fire Safety Design: A new approach to multi-storey buildings.
The new version of the software has been updated to align with the Eurocodes and also introduces a modified check on the resistance of the fire protected beams on the perimeter of the floor design zone.
TSLAB is available free of charge and is being released and distributed through the Corus website
The design methodology is based on calculating the load bearing capacity of the composite floor plate at a particular value of maximum displacement. The displacement can be predicted from knowledge of the thermal curvature of the slab and the elongation of the mesh.
The loss of mesh strength due to heating is also considered. The resistance calculations are based on yield line analysis and membrane action. Design may be based on the standard temperature time curve or parametric fire curves calculated in accordance with EN1991-1-2
New supporting SCI document P390 ‘TSLAB V3.0 user guidance and engineering update
Information on the revised user interface and to describe the new engineering features of TSLAB is given in SCI’s new supporting publication, which includes an illustrated worked example.
The publication also details some aspects of the engineering methodology which have changed between TSLAB versions 2.4 and 3.0, including the development of a new design method for edge beams.
