Abstract

In order to study the natural frequency of truss bridge, linear spring unit and bilinear model unit are separately used to simulate board rubber support and sliding support. Then modal analysis has been done by large-scale structure analysis software ANSYS in different support forms. At last, the results have been compared to explain that the forms of middle-rigid & end-flexible supports and middle-flexible & end-sliding supports are suitably used in the truss bridge.
