摘要:
结合自锚式悬索桥减震控制的研究现状,对大行程板式铅阻尼器在罕遇地震作用下的减震效果进行了分析研究。通过对比铅阻尼器和黏滞阻尼器的分析结果发现,在两种减震方案下结构的地震响应最大值(塔顶纵向位移、梁端纵向位移和塔底纵向弯矩)相差不大。可以说,只要阻尼器的选型(相关力学参数)恰当,大行程板式铅阻尼器的减震效果明显,且与黏滞阻尼器的相当。由于使用寿命长、构造简单、成本低,而且满足结构减震控制对大行程的需求,大行程板式铅阻尼器在独塔自锚式悬索桥减震控制中具有良好的应用前景。
Abstract:
The research on damping effect of a new kind of lead damper (Lead Damper with Long Stroke) has been done under rare earthquake on the combination of the status of the seismic control of a self-anchored suspension bridge with single-tower. Based on the results, the seismic response maximum (the longitudinal displacement of the tower top and the beam, the longitudinal moment of the tower bottom)of lead damper is almost the same to that of viscous damper. So, the damping effect of the lead shear damper with long stroke is good and it is close to that of viscous damper as long as the parameters are chosen properly. The structure of this kind of damper is simple, the service life is long and the processing cost is low. What’s more, it meet the demand of large displacement. So, it has a good prospect in damping control of a self-anchored suspension bridge with single-tower.
