In this paper, the finite element model updating method of the PSC bridge based on the static and dynamic data is verified through field experiment. The proposed method consists of two steps. First, update the rotational stiffness of the supports using the deflection and rotational displacement measurements that occur when the moving loads pass through the bridge. The stiffness of each member is updated by using the dynamic characteristics estimated from the acceleration measured by the ambient vibration test. The finite element model updated by the proposed method can predict the static and dynamic behavior of actual bridges through field experiment.
