框架结构抗震设计的简化分析方法

A Simplified Analytical Method of Anti-seismic Design of Frame Structure

在简化假设的基础上，推导出了规则框架结构自振周期、振型、地震作用、楼层剪力及水平位移等的解析表达式，并制成表格。利用本文结果，可方便地进行规则框架的抗震设计和抗震设防审查。算例表明，应用于一般非规则框架的抗震分析时，其精度也是令人满意的。

Analytical formulas for natural periods, vibration modes, earthquake actions, floor shear forces and hori- zontal displacementS of regular frame structures are derived out and tabulated, which can be uesd conveniently for seismic design of frame structrures and for examination of the results of these designs. Finally, several examples of irregular frames are given to test the effectiveness and precision of the method.
