摘要 重庆某大型商业裙房,为带部分剪力墙的框架结构,建筑和结构平面的开洞较多,就形成了薄弱连接的不规则平面。抗震设计中楼板应具备比抗侧力构件更高的抗震性能,针对本工程的结构特点,确定了楼板抗震设计性能目标及预期的震后性能状态,采用ABAQUS进行了结构整体的弹塑性时程分析,根据规范规定进行了楼板的受剪承载力计算,从内力和损伤进行了对比。分析结果表明,经过设计加强后的薄弱连接部位的楼板可以满足预定的性能目标。 A large commercial podium in Chongqing is a reinforced concrete frame structure with a small portion of shear walls. Due to the requirement of building use functions,there are large floor openings and the plane becomes irregular plane with weak connecting slab. In seismic design,floor should have better aseismic behavior than primary lateral load resistant systems. According to the structural characteristics of the project,the seismic design performance objectives and expected post seismic performance status of the floor is determined. The elastic-plastic time history analysis of the overall structure is conducted with FEM program ABAQUS. The shear capacity of reinforced concrete floor slab is calculated according to the code formula,comparison and analysis are made on the calculation results from the respects of internal force and damage. After strengthening,predetermined performance targets of the floor slab of weak connection can be met.
