| Abstract: |
In this research, we attempt to propose the introducing method of damping property of the viaduct system based on its damping mechanism. In this method, the damping factors of the viaduct system such as the internal material damping and the hysteresis damping of the pier and the superstructure, the frictional damping of the movable bearing and energy absorption at the base of the pier are incorporated into the numerical model of the integrated bridge structure. In order to confirm the validity of the method, we conduct the shaking table test of the simple specimen of the viaduct which includes the various damping factors, and conduct the dynamic response analysis of the corresponding numerical model employing the proposed damping modeling. The proposed damping modeling method can reproduce the elastic and inelastic behavior of the viaduct model employed in the shaking table test. |
