移动荷载作用下梁绝对最大弯矩计算的一种新方法

NEW METHOD OF CALCULATION FOR ABSOLUTE MAXIMUM BENDING MOMENT IN MOVING LOAD ACTION

在结构设计中,需要对梁的强度、刚度、稳定性等方面进行计算,其中绝对最大弯矩及位置的计算极为重要的。本文介绍了用一种计算梁最不利荷载位置及绝对最大弯矩的新方法,并用影响线进行校核,同时与传统方法进行比较。

In structural design, intensity stiffenss and stability need to be calculated, thereinto, calculation of absolute maximum bending moment and position is the most important. In this paper, new method on calculation of absolute maximum bending moment and position is introduced, and use influence line to check and compare to tradition method.
