竖向构件布置对梁式转换层结构刚度的影响

Effects of Vertical Components Layout to Transfer Floor Structure Stiffness of Beam

以一栋97.4 m的梁式转换高层建筑为研究模型,采用基于壳元理论的有限元软件SATWE进行分析,研究上部剪力墙的不同布置方式对结构刚度比、位移比、周期及底部剪力、底部弯矩的影响。详细阐述了结构上部剪力墙在不同布置方式下结构的刚度比、周期、底部剪力、底部弯矩的递变规律,得出一些有意义的结论,供设计时参考。

This article takes a transfer beam of 97.4 m high-rise tall building as the research model,using shell element theory based on finite element software SATWE to analyse the effect of the different arrangements of the upper shear wall structure stiffness ratio,displacement ratio and period and at the bottom of the shear and bending moment at the bottom.Moreover,this article elaborates the changing rules of the structure’s stiffness ratio,the natural period,the bottom shear force and the bending moment under different layouts, making some useful conclusion for references.
