EQUATION OF HORIZONTAL VIBRATION OF A MULTI-SPAN BRIDGE AND ITS APPLICATION TO MODEL TEST

The soundness of bridges when piers are not deeply embedded or soil is not stable is considered to be related to dynamic behavior of the piers. This paper gives an analytical method for horizontal vibration of a multi-span bridge with simple supports and then examines its application to a two-span model bridge. The effect of mass and the spring effect of loaded girders which influence pier vibration can be developed by using a simplified equivalent model.
