摘　　要： 分层法是计算框架在竖向荷载作用下内力的一种近似方法,该方法简单,计算量少,故常用于手算.但对于结构不对称或荷载变化较大的有侧移框架,仅用分层法计算内力往往会造成较大的误差.文章提出了联合应用分层法和D值法求解该类框架内力的方法,并以一个两层框架为例进行了对比分析.由于该方法考虑了侧移对框架内力的影响,所以使计算精度有较大的提高. Layer based moment distributing method is a method of approximation for calculation of sway frame subject to vertical loads. It is relatively a simple method with less calculating work. Therefore, this method is often used in manual calculation. However, it may result in errors which are not allowed in engineering practice. In this paper, by combining layer based moment distributing method with D-value method, the authors suggest a new method for calculating this kind of structure in which the influence of lateral displacement on internal force can be concerned. Numerical results show the new method has a higher calculation accuracy.
