论底层框架砖房倾覆力矩对框架的作用

就底层框架砖房处水平荷载 是如何传递到框架 上去的这 一问题，说 明了有 关规范的 近似 计算方法有时会有很大误差甚至根本不 适应；认为产生这种误差 或不适应 的主要 原因在 于计 算其倾 覆力 矩对框架的作用时只是采用一个力 系进行平衡，而未分析其荷载的具体传递情况，并以此 得知倾覆力矩 对框架到底是如何作用的另外，说明了在实际工程 中常用而又未 经论证的 计算方 法也 是不正 确的 为便 于实际运用，通过分析砖房部分水平荷载 的传递方式及力学特征，提出一个能较好的指导 实际工作而又 基本合理的计算方法，并通过实例演算，对上述问题 进行说明图８ ，参２

DISSCUSSION ABOUT ACTION ON FRAME BY CAPSIZING MOMENT OF A PRIMER-FRAME BRICK STRUCTURE

On the problem how the horizontal load of the brick structure transmits to the frame, this paper illustrated that approximate calculating method of the regime concerned cause considerable error sometimes, even complete unadaption. It's main reason that for the capsizing moment caused by horizontal loads we solely adopt one of force-system to balance it, without analyzing the transmission of the loads, thus how the capsizing moment's action on the primer-frame play a role can be known. Furthermore, this paper accounts for the calculation method without demonstrated, but used in many practical engineering are uncorrected. In order to facilitate operation in engineering, through analyzing the way of transmission of the brick structure horizontal loads and the condition of the static equilibrium, this paper introduce calculation method which can direct the practical work and is reasonable basically. and by demonstration of the samples, it made a total illustration for the problems as mentioned above.8figs.,2refs.
