摘要
为研究短肢剪力墙结构在地震激励作用下的地震反应,以钢筋与混凝土协同作用计算出的整体结构的等效模量方法为依据,对某实际短肢剪力墙结构试验设计模型建有限元模型,采用通用有限元ANSYS软件进行反应谱分析与时程反应分析。研究结果表明:基于“等效模量法”的计算结果可靠、准确,可揭示结构的薄弱环节;设置阻尼器可有效减小地震反应;T型短肢剪力墙比L型短肢剪力墙的抗震性能强。
In order to study the seismic response of short-leg shear wall structure under seismic excitation,based on the equivalent modu‐lus method of the whole structure calculated by the synergistic effect of reinforcement and concrete,a finite element model is built for the experimental design model of an actual short-leg shear wall structure,and the general finite element ANSYS software is used for response spectrum analysis and time history response analysis.The results show that the calculation results based on the"equivalent modulus method"are reliable and accurate,and can reveal the weak links of the structure;Setting damper can effectively reduce seismic response;The seis‐mic performance of T-shaped short-leg shear wall is stronger than that of L-shaped short-leg shear wall.
