【摘要】 框架结构中的填充墙不起承重作用，因此在框架结构设计及抗震分析中一般不进行详细计算。然而历次震害表明框架结构中的填充墙破坏严重，其对结构的抗震性能影响不容忽视。本文采用杆系有限元软件建立了不同砌体填充墙边界条件框架结构模型，通过与已有振动台试验结果对比得到了与试验结果最接近的砌体填充墙边界条件。然后采用该边界条件模型进行了模拟地震波作用下的结构响应分析。分析结果表明：在模拟地震波作用下，采用砌体填充墙边界条件与实际砌体填充墙与框架连接施工方法最接近的模型，得到的模型纵向加速度峰值和位移峰值与试验值吻合度较好。采用杆系有限元软件分析砌体填充墙与框架的边界条件对框架结构整体抗震性能影响简化分析的方法是可行的。更多还原

【Abstract】 The filling wall in the frame structure does not bear load, so generally it is no need to be calculated in the frame structure design and seismic analysis. However, it is shown in the previous earthquake disasters that the filling wall in the frame structure is seriously damaged, and its influence on the seismic performance of the frame structure can not be ignored. In this paper, the frame structure models with different boundary conditions of masonry filling walls are established by using the truss finite element software. By comparing with the data from shaking table test, the boundary condition of masonry filling wall which is most similar to the test results are obtained. Then the model with this boundary condition is loaded by the simulated seismic waves. The analysis results show that subjected to the simulated seismic waves, the model with the boundary conditions of masonry infilled wall which is the closest to the actual construction method of masonry infilled wall and frame connection is adopted, and the peak values of longitudinal acceleration and displacement of the model are in good agreement with the experimental values. It is practicable to analyze the influence of boundary conditions of masonry filling wall on the overall seismic performance of frame structure by using truss finite element software.更多还原
