本文研究不同类型梁式转换层的应力分布和转换梁高对结构位移变化的影响,运用ANSYS软件,对转换梁上部分别为剪力墙、框架和短肢剪力墙的三种结构进行了在竖向荷载作用下的应力分布及位移变化情况分析。结果表明:不同类型转换层结构在相同竖向荷载作用下应力分布差异较大,上部为剪力墙的结构转换梁内主要为拉应力,而其他两类结构转换梁内主要为压应力。转换梁截面高度的改变对上部整体刚度小的结构的竖向位移影响较大。通过对比分析,为转换层结构设计的结构选型及转换梁截面尺寸选取提供了参考。
In this paper, the different types of beam conversion layer stress distribution and the conversion of beam height on the structural displacement changes, the use of ANSYS software, the upper part of the conversion beam shear wall, frame and short-limbed shear wall of the three structures in the Analysis of Stress Distribution and Displacement under Vertical Load. The results show that the stress distributions of the different types of transfer floor structures are greatly different under the same vertical load. The tensile load of the structure transfer beam with the upper part of the shear wall is mainly tensile stress, while that of the other two types of structure transfer beams is mainly compressive stress. The change of the cross-section height of the conversion beam has a great influence on the vertical displacement of the structure with small overall stiffness of the upper part. Through comparative analysis, this paper provides a reference for the selection of the structure of the transfer layer structure and the selection of the cross-section size of the transfer beam.
