Abstract:
The finite element program ABAQUS was applied to study the numerical simulation of failure process of steel frame-RC corewall hybrid structure. The result shows that the concrete tube bored most of the horizontal force at the elastic stage of this structure, but steel frame carried most part of horizontal force once the corewall tube cracked. With the earthquake intensified, the steel frame carried the more and more horizontal force, which acted as the second seismic resistant system. Under earthquakes, cracks occurred firstly on the bottom of the corewall and almost the whole bottom was involved with the accumulation of damage, as well as the center of the floor cracked around the circumambience. The steel frame was on the elastic stage under moderate and heavy earthquake, but plastic cutter occurred firstly on the bottom column and then to the middle part of it under unusual earthquake. The remarkable deformation and a lot of cracks on the joint of corewall and steel frame beam of the floor were observed under earthquake. This structure in earthquake is a dual seismic resistant system.
