框架结构底层侧移计算

框架结构在水平荷载作用下的侧移计算手算通常用修正反弯点法（亦称＂Ｄ＂值法），此法计算框架结构底层侧移往往误差较大，本文提出一种新的计算方法，使用简便且精度较高。

CALCULATION ABOUT GROUND FLOOR DISPLACEMENT OF FRAME

When the horizontal loads act on the frame,tile method of noncomprterized calcuting horizontal displacement of ground floor of frame is used generally the amended method of point of inflection (or the Method of D Value). However,using these methods the results of calculation have much larger error. A new method is propeosed in this paper,the method is based on the analysis of a number of examples and obtain formulas of calculating displacement from this. The method has advantages of calculating,simplicity and an accurat result.
