摘要
本文采用连续化假定,将剪力墙作为竖向悬臂受弯构件,框架作为竖向悬臂剪切梁,由剪力墙与框架水平位移的协调条件建立体系的运动方程。在边界条件中,考虑剪力墙底部的剪切变形,求得结构前三个振型的自振频率、振型函数和振型参与系数,同时还给出了框架-剪力墙结构内力和位移的计算公式和计算表格。
The continuity assumption are made in the paper, i. e., assuming the shear walls as cantilever bending members and the frames as vertical cantilever shear beams. The differential equation of motion is established according with the compatibility conditions of displacement between shear walls and frames. Taking the shear deformation of the shear walls into accout in the boundary condition, the expressions of natural frequencies, modal functions and modal participations coefficients of the first three modes of structure are given, as well as the expression of the internal force and displacement of shear wall-frame system under earthquake loading are formulated, in addition, the corresponding tables for design purpose are provided.
