Zhu Zhangfeng' (1.School of Civil Engineering.Southeast Unisersity Nanjing Jiangsa 210096 China; 2.Nantong Construction General Contractor Co.Lad.Haimen Jiangsu 226124 China) Abstract:Reliability of shear wall and floor joint is the key for ploor to play transverse partition effect and make coordinated working with shear wall to form spatial force system.On the basis of finished tests and bining with finite element method detailed contrast and analysis has been done on various parameters affecting the joints'seismic capacity including different axial pression ratio of shear wall the strength diameter quantity and length of connection steel bar as well as the reinforcement ratio of floor.It is pointed out that the seismic performance of wall and floor joint for the new precast concrete shear wall structure is decided by the setting situation of connection steel bars and its coordinated working with m...
