摘要
为确定大型设施竖向隔振对弹簧支座抗震性能的要求,以盖板水平位移是否受限为基本条件,对 10 个弹簧隔振支座试件进行拟静力试验,基于试验结果探讨水平反复荷载与水平位移的关系,并提出有利于弹簧隔振支座有效使用的具体策略,以提升弹簧隔振支座的抗振性能,保证此类支座的稳定性.
Abstract
In order to determine the requirements of vertical vibration isolation of large facilities on the seismic performance of spring supports,pseudo static tests were carried out on 10 specimens of spring vibration isolation supports under the basic condition of whether the horizontal displacement of the cover plate was limited.Based on the test results,the relationship between horizontal repeated load and horizontal displacement was discussed,and specific strategies conducive to the effective use of spring vibration isolation supports were proposed.In order to improve the anti-vibration performance of the spring vibration isolation support and ensure the stability of this kind of support.
