“…Structural fire safety design mainly requires the study of the thermal environment caused by a fire, the heat transfer on components' surfaces, and the structural response to high temperatures. For steel structures, which are known to be vulnerable to fire, the peak can be around 600C degrees for fire-proof insulated components, and 1000C degrees for non-insulated components, which then collapse [5][6][7]. The measures taken for structural safety can also help to lock fire in one space and give the necessary time to evacuees.…”

Fire safety design of tall buildings is crucial. The number of floors, the function, and the occupants' features build the complexity in the life and fire safety design of tall buildings. Because of the complexity of each tall building design, specific preventive measures are necessary more than the basic requirements given in the national and local codes. The fire safety design of the world-renowned tall buildings, including Guangzhou International Finance Centre (IFC), Capital Market Authority (CMA) Tower, and Jin Mao Tower are case studies and further focus is made on the facade design of tall buildings. The paper reviews the safety design issues and focuses on the fire evacuation models, estimations, and the effect of different parameters in the success of fire safety design of tall buildings. In addition to the various fire evacuation suggestions, the effect of human behavior in fire is also discussed through the literature review. Fire safety is not only an engineering problem to deal with, but also architects must know the holistic approach in the fire safety design of tall buildings since it involves their architectural design as well. The paper aimed to bring the most arguable issues in the fire safety design of tall buildings together and to highlight the value of different perspectives in achieving a promising fire safety design.

“…Moreover, some crucial factors such as impact of local imperfections are still not fully recognised. In the result existing examples of such analysis are at the moment limited to just a few cases that have been recently described in [8], [12] and [13]. In this situation some further research is required.…”

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.

The paper presents the example of performance-based analysis for the existing large-space steel structure raised in 1980s. Hall is used as a paper products warehouse. Advanced mechanical simulations are performed using Safir software. Factors that impact the final fire resistance of the structure are discussed. Local and global imperfections and possible ways of structure modelling are taken into account. For selected cases advanced fire scenario that considers both localised fire and possibility of further ignition of stored goods is prepared using Fire Dynamics Simulation software. The results obtained indicate that added imperfections have little impact on the fire resistance of the structure and older-type steel hall roof without any fire protection could survive 30 minutes of fire. Main failure modes and values of structure’s deflections are also presented. Finally, performed simulations show that even for large-space structure the flashover is possible in some special cases.
