力法基本结构选取探讨

Study of Basic Structure Selection Force Method

力法是计算超静定结构最基本的方法,基本结构的选取是力法计算的关键。结合力法一般基本结构选取的方法,针对性的提出了超静定基本结构及混合不同基本结构的选取,并通过具体实例对比分析了其适用性,为正确、灵活选取力法基本结构提供参考。

Force method is the most basic method to compute the statically determinated structure,and the basic structure collection is the key problem of force method.In combination with normal force method basic structure selection,the statically determinated basic structure and mixed different basic structure are put forward pertinently,and the feasibility is verified by concrete examples,which established the foundation to choose force method basic structure correctly and flexibly.
