TY - JOUR N2 - The performance-based analysis of the large-space steel sports hall is presented. Load-bearing structure of the hall consists of spatial long-span truss girders that are made of modern square hollow sections. Both fire development analysis and mechanical response analysis are discussed in detail. Fire Dynamics Simulator and Safir programs are used. Main focus is put on the factors that could affect the final fire resistance of the structure. Uniform and non-uniform heating, different boundary conditions and local imperfections are taken into account. Structures with and without fireproof insulation are considered. Values of the critical temperature, failure modes and fire resistance estimated for various cases are presented. Computer simulations were carried out both for fire growth and decay phase. As a result it is clearly shown that some reductions of the required fireproof insulation are possible. Moreover, the structure without complete traditional fireproof insulation is able to survive not only the direct fire exposure but also the cooling phase.
