摘要
为探讨安装极低屈服点软钢阻尼器的钢框架结构抗震性能,对地震观测用的三层钢框架结构实施了拟动力试验,输入的地震波为该结构历年的地震观测记录.本次拟动力试验选用了4个地震波记录,分安装阻尼器和未安装阻尼器两种情况共计进行了8次试验.试验结果表明,软钢阻尼器可以有效地减小结构的地震反应,结构地震反应的试验结果和观测结果具有良好的一致性.
An experimental study on seismic behavior of steel frame attached with hysteretic dampers using ultra-low-yield-point steel was presented. The pseudo-dynamic tests were based on a scaled 3-story steel frame model that was constructed for earthquake monitoring. The pseudo-dynamic tests using various earthquake inputs, which were recorded by the sensor set in the site. The eight tests with and without hysteretic dampers u-sing four earthquake records. The case studies considered in offer great insight into the significant effect of hysteretic dampers. The comparison of response history results with monitoring and pseudo-dynamic tests agreed with each other fairly well.
