水平荷载作用下多跨高层框架的两种实用力矩分配法

TWO DISTRIBUTCL METHOD OF MULTISPAN AND MALTISTORY FRAME STRUCTURE UNDER HORIZONTAL LOODS

水平荷载作用下多跨高层框架精确计算的工作量很大，在工程设计中需要有一定精度的简便计算方法。本文根据梁跨中有反弯点的假设条件，建立了适合两种力矩分配法的实用计算方法，通过典型算例结果与精确解对比。

This paper fist deels with the mode of the frame structure under the horizontal loads. Then, two distributions of methods have been given for this problem.these formulas are not only simple, but also covenient and easy to calculate. Finally,several examples have been worked out with their results compared to the exact results,It is shown that the accuracy of the results computed by one or two distrution meet better the requirements needed in engineering practice than those obtained from conventional method.
