针对7层剪力墙结构缩尺模型振动台试验,比较研究基底固定和考虑土-结构动力相互作用两种条件下的钢筋混凝土剪力墙结构的抗震性能。分析结构在地震波作用下的加速度响应、放大系数、变形性能、应变分布情况以及结构模型的动力特性。在模型试验的基础上,进一步利用有限元分析软件ANSYS进行了剪力墙结构的动力反应分析,得到结构的自振特性以及在地震作用下动力响应的数值解,验证了ANSYS有限元数值分析方法的合理性。
Aimed at the shaking table test of 7-storey shear wall structure scale model, the seismic performance of reinforced concrete shear wall structure under two conditions of substrate fixation and considering soil-structure dynamic interaction is comparatively studied. The acceleration response, magnification factor, deformation performance, strain distribution and the dynamic characteristics of the structural model are analyzed under the action of seismic waves. Based on the model test, the dynamic response analysis of the shear wall structure is further carried out by using the finite element analysis software ANSYS, the natural vibration characteristics of the structure and the numerical solution of the dynamic response under earthquake action are verified, and the ANSYS numerical analysis method The rationality.
