某超限高层中混凝土V型斜柱的抗震分析与设计

Seismic analysis and design of the concrete V-shaped inclined column in an out-of-codes high rise building

在实际工程中交汇斜柱作为重要的抗侧力构件在抗侧力体系中发挥着重要的作用,但同时由于其具有受力复杂、钢筋锚固困难等特点,往往成为设计的难点。结合一具体项目案例,重点对项目中V型斜柱的设计和受力进行了讨论,同时通过YJK及midas FEA等分析软件,对V型斜柱进行了推覆分析和节点分析,设计的可靠性进行了验证。采用的分析和设计方法为类似项目提供了借鉴和参考。

As an important anti lateral force component,the intersection inclined column plays an important role in the anti-lateral force system. But at the same time,because of its characteristics of complex stress and difficult anchorage of steel bars,it often becomes the difficulty of design. Based on a real project case,this paper mainly discusses the design and stress of V-shaped inclined column in the project. At the same time,through YJK and midas FEA,the pushover analysis and joint analysis of V-shaped inclined column are carried out,and the reliability of the design is verified. The analysis and design methods used in this paper provide reference for similar projects.
