In the20th century, with China’s rapid economic growth, high-rise buildings areincreasing. The shear wall of architectural structure has gradually become a kind ofwidely used structure member in modern high-rise building for large lateral stiffnesswhich is useful for decreasing lateral and resisting earthquake force. But reinforcedconcrete shear wall easily happen brittle failure and this is very bad for the seismicperformance of the integral structure. A large number of tall buildings have sufferedserious damage after earthquake which fully explain that some seismic design theory andanalysis method are not systematic enough.So composite shear wall with concrete filledsteel tube has appearedCompression capacity of steel pipe concrete is very high. Failure pattern of thecompression failure is ductility. So it has a high capacity under vertical force. Compositeshear wall with concrete filled steel tube has good seismic performance and deformationperformance. Prefabricated structure system which is an effective way to bring abouthousing industrialization is the main research direction of housing industrialization.This paper puts forward prefabricated composite shear wall with concrete filled steeltube by researching papers domestic and overseas. To better research this compositeshear wall that concrete strength is C30and shear span ration1.67. We have designed twospecimens. One is a composite shear wall in situ, the other one is prefabricated.Specimens are loaded with low cycle reciprocating load.By comparing with theexperimental data, the capacity of normal section stiffness ductility damagecharacteristics can be studied.Compared with the composite shear wall in situ, the othercomposite shear wall which is prefabricated has good capacity and ductility. Afterreaching the limit load, prefabricated composite shear wall also has the good performanceof energy dissipation. |
