| 摘 要： | 大底盘多塔楼结构是底部相连上部分开的一种复杂结构形式。本工程由于立面收进要求采用竖向搭接转换块,目前对竖向搭接转换的结构研究不够充分全面。针对竖向搭接转换的结构形式,进行模拟地震整体结构振动台试验,并利用MIDAS软件进行整体结构分析。结果表明,采取搭接块的结构竖向刚度均匀,没有形成软弱层;大底盘与塔楼交界处的剪力突变,应采取适当的加强;裙房底部柱子应采取适当加强措施。

| Abstract: | A Multi-tower structure with large podium is a complex structure form which is connected at the bottom and departed at the top.The engineering in this paper adopts the vertical overlapping transitional block because of the requirement of the setback in elevation.However,the vertical overlapping transitional block is not fully studied at present.To study the structural form with the vertical overlapping transitional block,a shaking table test has been done and numerical analysis by the software MIDAS has bee... |
