摘要
揭示了超静定结构力法分析中的一个新现象,即力法分析不必只基于一个基本结构,还有同时基于两个不同基本结构的叠加公式,而传统的叠加公式只是本文所给叠加公式的特例.
A new inherent behavior in the analysis of statically indeterminate structures by the force method is discovered. A new superposition formula is established based on two simple structures. As a special case, the classical superposition formula can be obtained from the new formula given by present paper.
