| Abstract: | Based on the nonlinear ordinary differential governing equations of a beam resting on a elastic foundation subjected to uniform temperature increment and transverse load,and considering immovable clamped and movable simply supported boundary conditions,the numerical results of the ordinary differential equations two- point boundary value problem are obtained by shooting method.The effects of different parameters on the equilibrium route and the internal force distribution of the structure are investigated in detail. |
