本文在综合多层框架各种分析方法的基础上,认为最为合宜的方法是:在竖向荷载下应以无侧移的弯矩分配法最为方便;在水平荷载下则以有侧移的弯矩分配法,为最简捷。本文对后者用于多层单跨框架的分析作了说明。并对多层多跨框架结合倍数定理的应用,进行了论证和分析,从而可使手算所得的解答既简捷又精确,且还能编制简单的计算程序,可用袖珍计算机或计算器解算多层多跨框架的内力与变位。
Based on various analysis methods of multi-layer frames, this paper considers that the most suitable method is that the bending moment distribution method without side-shift under vertical load is the most convenient; when there is horizontal load, there is a curve with lateral displacement. Moment distribution method is the most convenient. This article explains the latter’s analysis of multilayer single-span frames. The application of multi-layer and multi-span framework combined multiple theorem is demonstrated and analyzed, so that the hand-calculated solution is simple and accurate, and a simple calculation program can be prepared. It can be solved with a pocket calculator or a calculator. Layers of multi-frame internal forces and displacements.
