| 摘 要： | 本文用逐次面积矩法解超静定梁。这是一种简单的方法,只要画出多余未知力的单位弯矩图,计算出它的面积,一次矩,二次矩,三次矩,然后按照梁上的载荷建立变形协调方程,多余未知力即可算出。

| Abstract: | In this paper,statically indeterminate beam were solved by successive order area-mo-ment method.This is a simple method.Only drawing united-load bending moment dia-rams of the unknown redundants.According to beam loading,we can calculate area,first moment,second moment and third moment of united-load bending moment diagramsand then can set up equation of compatibility of deformation,unknown redundants canbe calculated. |
