Design of Steelconcrete Hybrid Structure in Highrise Residential Buildings/Li Pining1,2,Qin Rong1(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 Mansionscientific model project in 2004,the application of steelconcrete hybrid structure technology is introduced in highrise residential buildings.The property of loadbearing capacity and the performance of elastoplastic are analyzed.The members and joints are designed and antifire 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:highrise residential building; hybrid structure; rectangle concretefilled steel tubular (CFST); antifire design; differential shortening between columns and walls
