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
The question of how the horizontal load at the bottom frame brick house is transmitted to the frame indicates that the approximate calculation method of the relevant specification sometimes has a large error or even no adaptation; the main reason for this error or incompatibility is that To calculate the effect of the overturning moment on the frame, only a force system is used for balance, and the specific transmission condition of the load is not analyzed, and the effect of the overturning moment on the frame is explained. In addition, it is explained in the actual project. The commonly used and unproven calculation methods are also incorrect. To facilitate the practical application, by analyzing the transfer methods and mechanical characteristics of part of the horizontal load of the brick house, a computation method that can guide the practical work and is basically reasonable is proposed. And through the example calculations, the above problems are explained (Figure 8).
