STUDY ON THE DESIGN METHODS TO RESIST PROGRESSIVE COLLAPSE FOR BUILDING STRUCTURES
Since the collapse of the Ronan Point Tower in United Kingdom in 1968, the progressive collapse resistance of building structures has attracted a global attention. Important foreign design codes have developed their specifications for building structures to resist progressive collapse, but the related research is still lack in China. This paper presents a series of researches by the Department of Civil Engineering in Tsinghua University on progressive collapse resistance of building structures.The existing design methods are briefly summarized, and two major design methods, which are alternate path (AP) method and tie force (TF) method, are proposed together with feasible procedure and carefully studied factors that are suitable for Chinese structures. The effects of each proposed methods are verified with nonlinear dynamic simulations and the additional cost due to progressive collapse resistance design is compared.
