高烈度区新型减隔震连续梁桥的抗震性能
Seismic performance of new isolated continuous bridge in high intensity region
摘要
Abstract
Considering both the energy-dissipation capacity and the deformability adaption to envi-ronmental actions during the service period of a bridge, a new multi-function isolation bearing is pro-posed.Taking the Taibai Bridge in a high intensity region as an example, the seismic mitigation effect of the new isolation bearing with experimental parameters on the continuous bridge is analyzed in time domain.And the performance of the new isolation bearing is compared with those of the non-isolation system, the sliding isolation bearing and the lead rubber bearing.The results show that the new isolation bearing has good control effects.It has superior adaptability to the deformation of the bridge under the actions of environment.And the energy-dissipation requirement can be well satisfied during strong earthquakes so that the structural safety can be assured.关键词
