连续梁挠曲线的新解法

An other Method of Evaluating Deflection Curve of a Continuous Beam

当用二次积分法求梁的挠度和转角时,粱的每一段都有两个待定的积分常数。为了简化积分常数的处理,对弯矩方程的写法和积分变量的使用提出了限制。但是,当粱上有分段的分布荷载时,上述方法也无能为力了。本文提出了积分常数的另一种处理方法,使得积分常数的处理简化,同时又避免了上述方法的局限性。

We evaluate deflection Curve of a Continuous beam by using method of Successive integraton, There are two Constants of integration for every span of the beam[1] . In order to determine these constants Succinctly, We Can impose restrictions on expressions of the bending moment equations[2]. However, when threr is uniform load on certain span, the above -mentioned method isn't valid.In this paper, we give another method to evaluate deflection curve of a continuous beam.This method is that deflection Curve of the continuous beam is evaluated by the definite integral on the every span of the beam.If you use the method, then determining the deflection Curve of a Continuous beam is facilitated.
