带斜柱转换的某高层建筑结构设计

Structural Design of a High-rise Building with Inclining Columns

地震作用下带斜柱转换的高层建筑结构受力复杂,容易形成薄弱层。针对某一带斜柱的高层建筑结构,采用合理的结构布置,通过两种三维有限元程序进行整体对比、弹性时程分析及关键楼板的应力有限元分析,并加强构造措施,使得结构整体和各构件的抗震性能达到设计目标。本文通过工程实例阐述了此类结构的设计要点及应注意的问题,供类似工程参考借鉴。

The internal forces of the high-rise building with inclining columns under earthquake are complicated,and to form weak layer easily.For a high-rise building with inclining columns it is very important to select a rational structural layout scheme.The analysis through the comparison of two three-dimensional finite element software,elastic time history analysis and stress analysis of the key floor slabs have been competed,and different construction detail have been carried out to make the seismic behavior of whole structure and each structural member reach the expected objective.Through a project case this paper expounds the point of structural design and some problems that should be paid attention to,which is as the reference for the similar project.
