Design of Steelconcrete Hybrid Structure in Highrise Residential Buildings/Li Pining1,2,Qin Rong1(1 Guangxi Institute of Architectural Design & Research,Nanning 530011,China; 2 Civil Engineering College,Guangxi University,Nanning 530004,China)
Abstract:Based on the design of Nanning Hubin Mansionscientific model project in 2004,the application of steelconcrete hybrid structure technology is introduced in highrise residential buildings.The property of loadbearing capacity and the performance of elastoplastic are analyzed.The members and joints are designed and antifire design method of rectangular CFST column is studied.The differential shortening between steel columns and reinforced concrete walls is analyzed,and measures decreased differential shortening are put forward.
Keywords:highrise residential building; hybrid structure; rectangle concretefilled steel tubular (CFST); antifire design; differential shortening between columns and walls
