【摘要】 结合实际工程的抗震性能分析,探讨罕遇地震作用下楼板局部不连续对结构抗震性能的影响。分析结果表明:对于墙体布置均匀的剪力墙结构,其抗震性能受楼板影响较小;而对于依靠楼板传递水平剪力的框-剪墙结构,楼板对其抗震性能影响较为明显。合理布置结构平面是保证楼板局部不连续结构抗震性能的关键。更多还原

【Abstract】 Based on the seismic analysis of the ultra-limit high-rise shear wall structures and frame-shearwall structure,the influences on the seismic performance of the structure characterized by floor partial discontinuity are discussed under rare earthquake.It is shown that the seismic performance of shearwall structure,with uniform arrangement of shearwalls,is less influenced by the floor. The seismic performance of frame-shearwall structure,relying on the floor to transfer shear force,is seriously influenced by the floor.Appropriate structure arrangement is the key to ensure the seismic performance of the structure.更多还原
