초록
For more districted seismic design and attemped multi-bridge continuity, the existing seismic design is difficulted to treat seismic activity. So, many company applied multi-fixed point and damper or isolator, which is effective for decreasing seismic energy, on period shift, decentralization and damping. But, there is hard to design special bridge with adjusted seismic system because of absence seismic device and insufficient design experience. Therefore, the study on behavior characteristics of designed bridge with various seismic device is performed to utilize the result of this for selection of adequate seismic device.
