摘要
为了研究地震作用下不同因素对调频液体阻尼器(tuned liquid damper,TLD)在高层建筑减震效果的影响,以一高层剪力墙结构为研究对象,通过有限元软件SAP2000建立实体模型,在考虑液体的动力特性的基础上,对TLD在地震作用下的影响因素进行动力响应分析,研究质量比、刚度比、阻尼比对结构的减震效果的影响规律及参数优化设计。并为工程提出相关的建议,为以后的高层设计及相关规范的制定提供参考。
In order to study the influence of different factors on the damping effect of tuned liquid damper(TLD)in high-rise buildings under seismic action,this paper takes a high-rise shear wall structure as the research object,and the solid model is established through the finite element software SAP2000.On the basis of the dynamic characteristics of liquid,the dynamic response analysis of the influencing factors of TLD under earthquake are carried out,and the influence law of mass ratio,stiffness ratio and damping ratio on the damping effect of the structure and the parameter optimization design are studied.Then some relevant suggestions for the project are put forward,so as to provide reference for the future high-rise design and the formulation of relevant specifications.
