结构分析中应用力法简化自由项的新方法

A New Approach of Simplifying Free Term by Force Method in Structure Analysis

用力法分析荷载作用下的超静定结构内力时 ,在受力等效、位移协调的条件下 ,通过选用不同的基本结构 。

A new method will be promoted to simplify the calculation of the free term, when structure's inner force behavior is analyzed through forth method which is confirmed by examples. It will provide a reference during the structural mechanics course and analysis of engineering structures.
