| Abstract: | A model for simulating nonlinear soil-structure interaction of Integral Abutment Bridges is presented in dynamic analysis of this bridges. Based on this the finite element model of a integral abutment bridge is built and the vibration properties(mode shape、frequency.etc) of the structure are analyzed. Then the influence of soil reaction to the dynamic characteristic of structure is examined and the chief parameters that influence strongly it are found out﹒The results can help to unterstand the dynamic properties of this bridges. |
