结构混合耗能控制研究

Study on Structural Control of Hybrid Energy Dissipation

针对调谐液体阻尼器 (TLD)对地震动输入前期的结构响应控制作用较差的情况 ,采用了粘性液体耗能器与TLD联合作用的混合耗能体系进行地震动响应控制 .通过钢框架 -混合耗能体系的地震动响应数值分析 ,比较了独立TLD阻尼器与混合耗能体系的减振效果 。

The hybrid energy dissipation system consisting of tu ne d liquid damper (TLD) and viscous fluid damper (VFD) is suggested to control the seismic response of structures for counteracting the deficiency of TLD in contr olling the seismic response of the structures at the beginning of the seismic ex citation.By the numerical analysis for the seismic response of a steel frame str ucture with energy dissipation system,the efficiency of reducing vibration is co mpared between energy dissipation system only with TLD and those with hybrid TLD /VFD.The effect of VFD on the combination energy dissipation system is also stud ied.
