ABSTRACT
This chapter introduces the structural fire design procedures for steel, concrete, and composite structural members based on Eurocodes and British Standards. It also introduces the two key structural fire design methods, namely, critical temperature method and moment capacity method. The primary task for structural fire design is to design the fire resistance of structural (load-bearing) members such as beams, columns, wall, and slabs to ensure that they won’t fail within the required fire rating duration specified by various codes. In a tall building, building elements to be considered primarily in design for fire are as follows: structural frames, floors, load-bearing walls and compartment wall. The critical temperature of a member in a given situation depends on the load that the member carries under fire condition. The moment capacity method can be used for the design of composite slabs under fire. The thermal profile shall be worked out, from which the reduced strength of the concrete and steel can be calculated.
