快捷绘制梁的内力弯矩图方法研究

经比较实际结构工程中设计梁构件时梁内力弯矩的两种计算方法截面法和叠加法,得知截面法的计算过程较为繁琐而叠加法较为简捷,对叠加法的应用条件、范围、初学者运用此法的问题也作了阐述。

Study on Methods of Calculating Internal Force of Girder Curve- moment

"Sectional method" and "additional method" are the most commonly applied two methods of calculating the internal force of curve-moment of girders in the engineering design. It was found by comparison that the "additional method" was a faster and better one than the "sectional method". The conditions and scope of application of the "additional method", and the problems might be met by beginners applying the method were discussed.
