The emphasis is placed on investigation of the influence of the coherency between different components of same and different supports to the bridge. First, the MSRS method proposed by Kiureghian is extended to account for multi-component multi-support excitations. Then, parametric analyses of coherency to the structural seismic response are performed. The conclusions are drawn as follows: The coherency between different components of same and different supports should be considered in order to guarantee the safety of the bridge. Amplification factors are introduced to account for the influence of coherency, and simple calculation method is obtained to account for the multi-component and multi-support effect.
