| Abstract: | Through the construction practice of a beam-arch composite bridge,conducte a stress anslysis for a model of the partial structure by using the space finite element analysis software.The characteristics of the bridge under different force are simulated in order to get the distributing of stress.Some problem that cannot be found in the routine anslysis for internal force are revealed. |
