摘要/Abstract

摘要： 在传统的力法中,无论是力法基本方程的建立,还是系数和自由项的求解,都要求在同一基本结构上进行。本文中采用的方法是选取两个不同的基本结构,对其力法方程和叠加公式进行了证明,通过实例验证了文中方法的正确性,为力法分析提供了新的求解途径。

Abstract: In order to obtain the canonical equation or to solve for the coefficients in the equations, a proper primary structure is required in the traditional force method. In this paper, the force formula and the superposition formula derived from the two primary structures are constructed and verified by examples. And thus it yields a new approach to the analysis of statically indeterminate structures.

Key words: statically indeterminate structure, primary structure, force method, superposition formula
