SRC Structure Application of Literature Building in Shenzhen University/Ba Guijiang,Zhang Jun,Zhang Liangping(Huasen Architecture & Engineering Design Consultants Ltd.,Shenzhen 518054,China)
Abstract:The structure stiffness of Literature Building in Shenzhen University is irregular.The upper is stiff and the lower is soft.The shape steel RC columns and beams are used to improve the structural seismic performance.The joints design of shape steel RC beams to columns,the primary beams to secondary beams,and the shape steel RC beams to steel tube RC columns is introduced. The software SATWE and ETABS are used to analyse the structure. The results show that the deformation performance of the structure is improved,and bearing capacity cauld meet the demand.The construction measures of the SRC structure and the technique of ensuring the engineering quality are concluded.
