Fire Protection Design for Steel Staggered-Truss Framing System Based on Mechanical Performance Calculation

Abstract:

An optimizing strategy, based on the performance calculation of mechanical properties under high temperature, was proposed to study the method of fire protection design for steel staggered-truss framing system (SSTFS). That is, the whole elastic-plastic process of the structure is investigated using the finite element method firstly, and the components which appear plastic deformation easily are found, and then their fire resistance rating would be enhanced especially. In comparison with the traditional regular fire protection strategy, it is confirmed that the fire resistant capacity of the SSTFS can be improved dramatically. And the security of the structure could be ensured, while the required volume of fire protection coatings is reduced.
