摘要
采用连续化方法，将框架作为竖向悬臂剪切梁，剪力墙作为竖向悬臂受弯构件，得到框架结构前三阶振型和频率，按振型分解反应谱法基本原理，推导出框剪结构内力和位移的计算公式和表格。文中还给出一个算例，并与底部剪力法对比分析以表明此方法的优越性，供设计人员参考。
The paper introduces the way in which the basic principle of the decomposing reaction spectrum of the mode of vibration is followed to derive the formula and tables of the internal force and displacement of the frame-shearing wall structures from the previous three-stage vibration models and frequency of the frame - shearing wall structure obtained by using the succesion method, with a frame taken as the hill - dale shearing overhanging beam and a shearing wall taken as the hill - and - dale overhanging flexural member. In order to exhibit its advantages, as proved by comparing bottom-shearing method for analysis, the paper offers a calculation example to serve as a reference for designers.
