Title: Antiplane dynamic soil‐bridge interaction for incident plane SH‐waves
Abstract: Abstract The analysis of dynamic soil‐bridge interaction has been performed in three steps. These are: The analysis of input motions. The force‐displacement relationships for the foundations. The dynamic analysis of the structure itself, i.e. the bridge. Based on the exact solution of the first two steps, the dynamic interaction of a simple two‐dimensional bridge model erected on an elastic half‐space has been investigated for a single span case. The two‐dimensional model under study consists of an elastic shear girder bridge supported by two rigid abutments and rigid foundations which have a circular cross‐section and are welded to the half‐space. It has been shown that the dynamic interaction depends on: The incidence angle of plane SH‐waves. The ratio of the rigidity of the girder and the soil. The ratio of the girder mass to the mass of the rigid abutment‐foundation system. The span of the bridge. The dynamic response of the girder and the effect of the radiative damping in the half‐space on the interaction of the girder have been studied.
