Effect and Measure of Cast-in-place Floor Slab on Strong Column Weak Beam Mechanism of RC Frame Structures
摘要
Abstract
Taking Xuankou Middle School building in Wenchuan collapsed in the earthquake as the prototype,two RC frame com-parison models were designed,namely,the ordinary cast-in-place floor frame model and the frame model with gaps at four cor-ners of the floor.The nonlinear finite element time history comparison analysis was carried out by DIANA.The analysis shows that the RC frame structure is difficult to realize the failure mechanism of"strong column and weak beam"due to the existence of cast-in-place floor slab.The measure of slotting at four corners of the floor slab,making separate between slab and beam,can effective-ly reduce the number of plastic hinges at the column end of the frame structure,so that the structure presents a failure mechanism of"strong column and weak beam"and improves the ductility and seismic performance of the RC frame structure.关键词
