用求荷载控制段的方法确定临界荷载

Determining the Critical Load by Finding the Controlled Segments of Loads

提出在移动荷载组作用下求简支梁内某一指定截面的最大弯矩的一种解法，这种解法的关键是求出梁上各个荷载的控制段．

A simple and workable computing method was presented to the the maximal moment on a certain section inside a simple which a group of moving loads acted upon.The key of this method is to find out its controlled segment on that beam corresponding to each load.
