This bridge is named Houzhu Bridge, in Quanzhou, Fujian province. There is no material difference between the result of the 3-D finite element model modal analysis and modal test that confirms the 3-D finite element model reasonable. The ground motions come from relatively non-stationary earthquake accelerograms simulation with EI-centro wave. Wave passage effect, incoherence effect and local effect is consider in the numerical simulation. The contrast of results multi-support excitations and uniform excitation is that the wave passage effect is very important for the continuous rigid frame bridges, the other effect is not very important. A conclusion is given that the uniform seismic excitation is not able to control the seismic design for long span prestressed concrete continuous rigid-framed bridge, and the influence of the multi-support excitations on the seismic responses of the long span prestressed concrete continuous rigid-framed bridge must be considered.
