附加调谐质量-颗粒阻尼器复合减振体系的钢框架结构振动台试验研究
Shaking table test on steel frame structures with combined damping system with TMD and particle damper
摘要
Abstract
To investigate the effect of a combined damping system,formed by the parallel connection of tuned mass damper(TMD)and parallel single-dimensional single particle damper(PSSPD)(named the combined damping system with TMD and PSSPD,or CTP),and its arrangement scheme on the seismic performance of multi-layer structures,a three story steel frame structure model with a scale ratio of 1/5 was constructed,and shaking table tests were conducted under five natural ground motions.The damping effects of CTP and TMD were compared and analyzed.Based on the dynamic characteristics of the experimental structure model such as mass,natural frequency,and vibration mode,the TMD and three layout schemes of CTP were designed.The displacement and acceleration responses of the structural model and the mass block under different damping schemes were analyzed.The test results indicate that the CTP can achieve the average damping rates of 16.74％and 21.90％for the peak response and the root mean square of the responses,respectively,which demonstrate that CTP has a good damping effect on multi-story structures.The damping effect of CTP on the root mean square of structural dynamic response is better than that on the peak response.The arrangement scheme of CTP significantly affectes its damping effect,and the optimal damping effect is achieved when the particle mass is distributed according to the first-order mode of the primary structure.Under the same mass,CTP has a better damping effect,and the mass block has a smaller amplitude of relative displacement and thus enters the working state earlier,compared with TMD.Meanwhile,a mechanical model for multi-layer frame structures equipped with CTP and its numerical simulation methods were proposed.The results show that the maximum average relative error between the experimental and simulated values of the peak displacement and root mean square value of the model structure is only 13.20％,and the error is controlled within an acceptable range.关键词
