分跨等值连续梁的奇异函数解法

A Method of Calculating the Continuous Beam of Dividing Span of Equivalent Cross-section by the Singularity Function

连续梁在工程结构中有着广泛的应用。本文采用奇异函数解法,直接求得分跨等值连续梁的支座反力,使该静不定问题归结为解一个矩阵方程式,并且得到小变形情况下的精确解。用 BASIC 语言编写了计算程序,使该方法更为实用。

Continuous beam is widely used in engineering construction.In this paper, the singularity function method is used to get directly the reasons of continuous beam of dividing span of equivalent cross-section.So that solving a statically indeterminate problem can be simplified into solving a matrix equation.The accurate solution can be gained in the case of small deformation.A calculating program in BASIC language is compiled to make the method more practical.
