Though collapse should theoretically be avoid for any buildings under any earthquake, it is still very important to study the collapse behavior of buildings so as to get a better understanding for the collapse mechanism and to find efficient method to against it. Progressive collapse, which means that collapse of whole building due to local weak stories or weak zones, is a most common failure mode in earthquake. And as its collapse process highly depends on the whole structural system, numerical simulation becomes a major method to study it. With the fiber-beam-element model and multi-layer-shell-element model, which is developed by Tsinghua University for reinforced concrete (RC) frames and RC shear-walls respectively, the extreme nonlinear behavior of RC structural elements can be properly simulated including the cycle behavior under coupled axial force-bending moment-shear force, the breakdown of structural elements at ultimate states, and the contact between structural elements during the collapse. Simple RC frames and RC frame-shear wall structures are firstly used to demonstrate and to benchmark the capacity of the numerical model, and real complicated buildings are analyzed to study the failure mechanism of the structures.
