某超高层建筑底部斜柱转换的结构设计与分析

对某底部斜柱转换的高层建筑结构进行整体结构分析、多遇地震作用下的弹性时程分析以及罕遇地震作用下的动力弹塑性时程分析,并对斜柱对结构整体的影响、斜柱传力、斜柱层楼板应力以及斜柱节点设计进行了专项分析。根据计算分析,对关键构件及部位从计算和构造两方面采取加强措施,使结构整体及各构件的抗震性能均能达到设计的预期目标。

Structural design and analysis of inclined column transfer at the bottom of a super high-rise building

The whole structure analysis,elastic time-history analysis under frequent earthquakes and dynamic elastoplastic time-history analysis under rare earthquakes were carried out for a high-rise building structure transferred by inclined columns at the bottom.The influence of inclined columns on the whole structure,the force transmission of inclined columns,the floor stress of inclined column layers and the design of inclined column joints were specially analyzed.According to the calculation and analysis,strengthening measures were taken for the key components and parts from both calculation and construction,so that the seismic performance of the whole structure and each component could reach the expected design goals.
