摘要
旨在研究不同转换梁线刚度对基础隔震框架-剪力墙结构受力性能的影响,基于有限元软件ABAQUS建立框架-剪力墙精细化模型,通过改变隔震层转换梁尺寸对比模型在单向加载条件下塑性发展、承载力及支座面压变化。结果表明,提高隔震层转换梁线刚度有利于减轻隔震结构的破坏损伤,提高结构极限承载能力,减小隔震层支座面压。
The purpose of this paper is to study the effects of different transfer beam stiffness on the mechanical behavior of the base-isolated RC shear-wall frame structure.Based on the numerical model established by finite element software ABAQUS,the shape development,bearing capacity and bearing surface pressure of the model under unidirectional loading conditions were compared by changing the size of the isolated beam of the isolation layer.The results show that the lifting beam stiffness of the isolated beam is beneficial to alleviate the damage of the isolated structure,improve the ultimate bearing capacity of the structure,and reduce the surface pressure of the isolation layer.
