| Abstract: | Two modified complementary energy principles which only require C0 fields are derived in this paper. It is pointed out that if the fields of moment and deflection satisfy the respective second order homogeneous differential equation then they can both be considered as independent of each other and satisfy the equilibrium equation. The linear fields of moment and deflection are used in finite element analysis. The calculated results show that the method used in this paper is simple and reliable. |
