| Abstract: | In this paper,the differential equilibrium equations are established in the deflected state and the axial force effect on the deflected state is considered,and the physical relations are discussed.The matrix displacement method is used to establish the structural stiffness equations and the equations are written in the form of iteration in order to analyze the second order internal force.The results of the example in this paper are compared with that in the case of the first order internal force,and some useful conclusions are gotten. |
