THE STUDIES ON COLLAPSE RESISTANT CAPACITY OF MULTIRIBBED COMPOSITE SHEARWALL EMBEDDED STEEL
Based on contrast multi-ribbed composite wall structure and full RC shear wall structure, the multi-ribbed composite shear wall embedded steel (MCSS) is put forward and introduced in this paper, which is a new energy-dissipation structure on the basis of controlled seismic response theory. The finite element model of MCSS is created to simulate its seismic performance by ANSYS programs. Such key factors as elements selecting, constitutive relation and failure criteria of materials, connection of different members, and cracking of concrete are considered. The bearing capacity, deformation performance, energy dissipation ability and skeleton curve of MCSS are presented and compared. The results of analysis indicate that full-course of MCSS failure go through elastic stage, plastic stage and failure stage with lateral loads and moment action increasing. It is proved that the steel pillar embed in the fringe frame of MCSS could strengthen moment action resistant capacity, and the precast multi-ribbed composite slabs infill in the abdomen of MCSS could reduced its deadweight and ratio of steel. The Studies show that the excellent collapse resistant capacity is provided by MCSS.
