摘要
采用频率响应函数(FRF)分析方法,通过对带能量吸收器的管道动态特性及地震响应的实验研究,探讨了能量吸收器对管道阻尼特性的影响,验证了阻尼器削减后能量吸收器在管道中的的减震效果。实验结果表明,能量吸收器进入塑性后,能够提供较高的阻尼比,较大地降低管道的地震响应。
Making use of frequency response function analysis method, testing study on dynamic behavior and seismic response of pipe with energy absorber is performed in this paper. Through analysis, the influence of energy absorber on the damping behavior of pipe is explored, the reducing seismic response effect of energy absorber in the pipe is also verified after snubbers is slashed. The testing results show that the energy absorber can provide higher damping ratio and reduce the seismic response of pipe largely after it is strained beyond the yield point.
