摘　　要：采用三维力学模型对底部框架-抗震墙房屋中的底部框架-抗震墙部分单独分析时,恒、活、风荷内力可直接采用,地震作用效应根据抗震规范要求需要调整。本文提出了墙、柱地震作用效应调整方法。该方法可适用于采用各种剪力墙模型的三维计算软件。A multi-story masonry building with frame-shear walls on first or first and second floors consists of two parts, i.e., the bottom frame-shear wall and the upper masonry component. By using a 3-D analysis program, the internal forces under dead loads, live loads and wind loads in the bottom flame-shear wall part can be directly employed, however, the earthquake action effects, according to the Cede for Seismic Design of Building, need to be adjusted. In the present paper, an earthquake action effect adjustment method is proposed, which is applicable to various 3-D analysis programs with different shear wall models.
