Static Elastic-plastic Pushover Analysis About Steel Reinforced Concrete Composite Affected By Earthquake

China is one of the most disasterous countries which suffer from earthquakes. The earthquake brings great disasters to human being, these disasters are mainly caused by destruction from the buildings and engineering facilities with low-quality seismic protective function. With the development of technology, the traditional concrete structure cannot satisfy the need for seismic protective function of modern building, so SRC is applied to improve seismic protective function of modern building, that is to say, the SRC is applied in the critical part of the structure and the common concrete member in the other part.In the paper, the finite element method software is applied to analyze the seismic protective function by static push-over analysis . The developing process of plastic-hinge, Storey displacement, Storey-drift-angle displacement, the relationship between Capacity Spectrum and Demand Spectrum of SRC affected by M8 usual and rare seismic force are researched to analyze the anti-seismic behavior and ductility. The research above can inspire the design of SRC,even the development of modern construction.
