摘要:
在满足支座耗能能力的同时,兼顾其在桥梁运营期间的变形适应能力,研发了一种新型多功能减隔震支座.以地处地震高烈度区的太白大桥为研究对象,基于实测参数分析了时域内新型支座用于该连续梁桥的减震效果,并分别与传统非隔震体系、摩擦滑移支座隔震、铅芯橡胶支座隔震等措施的减震效果进行了对比.结果表明,新型减隔震支座具有较好的综合使用效果,对桥梁在环境作用下的变形适应能力较强,并且可以满足桥梁在强震下的耗能需求,保证了桥梁的安全性.
Abstract:
Considering both the energy-dissipation capacity and the deformability adaption to environmental actions during the service period of a bridge, a new multi-function isolation bearing is proposed. 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.
