Abstract

In order to analyze the static and dynamic characteristics of an under-supported truss bridge, the laboratory truss bridge model is established, and the displacement and strain data are measured by the sensors laid on the bridge model. Then two different finite element model software are used to create the bridge element by nodes, and two finite element models of the under-supported truss bridge are established respectively. The static analysis of the model is carried out to obtain the internal force and deformation of the bridge model under different working conditions, and the stress of the bridge is understood. After comparing the finite element model with the laboratory model data, the static characteristics of the truss bridge are obtained, and the reliability of the finite element models simulated by different software is analyzed and verified. Finally, the dynamic characteristics of the model are analyzed by finite element analysis method.
