A force method equation in the analysis of statically indeterminate structures based on different basic structures
Abstract：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.
