A Safe and Economical Design of Composite Profile Steel Decking Systems under Fire Conditions

Due to two fire incidents viz. the Basingstoke and the Broadgate Fires, composite slabs consisting of steel beams and lightly reinforced concrete slabs with steel decking showed an inherent load-carrying capacity in fire by mobilizing tensile membrane action at large displacements. Based on a number...
