Simple Calculation Method of Fire Resistance of Continuous Composite Steel and Concrete Beams
A simple calculation method providing a practical design rule to calculate the fire resistance of a usual type of composite steel and concrete beams is proposed. This method developed on the basis of experimental investigation permits to calculate, on the one hand, the load bearing capacity of continuous composite steel and concrete beams related to global element collapse through sagging and hogging moment resistances for a given fire duration. On the other hand, it takes account of local collapses of continuous composite beams under fire situation, such as the local resistance at supports related to steel local buckling and crushing. Furthermore, the method is also applicable to continuous composite beams with partial shear connection. Examples comparing the proposed simple calculation method and several fire tests will be shown in this paper, which gives evidence of the validity of the method.
