- EVALUATION OF SEISMIC RESPONSE OF A PC CABLE-STAYED BRIDGE SUBJECTED TO A LONG-PERIOD GROUND MOTION AND EFFECTIVENESS OF DAMPERS
抄録
The mechanisms associated with the seismic response of a PC cable-stayed bridge subjected to a long-period ground motion are clarified by nonlinear seismic response analyses using the simulated long-period excitations in the anticipated Nankai earthquake. A maximum displacement of 0.794m occurs at the tower top, which causes the damage to the tower bottom and tension variation of ±7.8% to the initial tension in the cables. The large residual displacement of 0.058m occurs at the tower top due to the increase of curvature at the tower bottom subjected to the subsequent ground motion. The effectiveness of the installation of viscous dampers between a deck and cables to reduce the tower response, is revealed.
