力法分析中,冗余约束力和荷载可以基于不同基本结构求解超静定问题.采用卡氏定理,推导了力法新的分析方法基本方程,证明了在力法分析中可以混合采用不同的基本结构建立力法基本方程和求解自由项,并对新的基本方程的物理意义进行了分析.算例分析表明,该方法计算简单,结论正确,有助于进一步认识力法.

Redundant restraint loads acted on different basic structures can be supposed as unknowns for solving statically indeterminate structure by force method.The basic equation of improved force method was derived by castiglianos theorem.It was introduced and verified that the basic equations and the coefficients in the equations can be obtained and found by different basic structuces.Meanwhile the physical significance was discussed of the new basic equation.The example showed that the method introduced herein was correct,and easy to apply.It was also helpful for us to understand the theory of the force method.
