| Abstract: | In this paper, the author analyzed the problems of nonlinear RC frame structures, and advanced an intuitionistic and practical finite element method in which the basic element was minimized, and the more simple B -N- M curve was employed, eventually the problems was solved by the hybrid method. At the same time, a nonlinear finite element program is completed by Fortran 90, which simulated the performance of RC structures after and before cracking and the crushing in the concrete. |
