Fire safety design of composite slim floor structures

摘要

A structural fire safety design method for composite steel-concrete slim floor structures was developed, including the characterization of fully-developed compartment fire curves and the equivalent fire exposure, temperature analysis of the composite structures, and the structural response analysis of composite slim floor structures subjected to fire. Special interest was given to the structural responses of the slim floor beam both as an isolated member and a part of the frame structure. The mechanical interaction behind the global deformation response of the frame was emphasized.Although the analyzed objects concentrated on composite slim floor structures, the according fire safety design method and the explored structural response mechanism in fire are equally applicable to other types of building structures.
