【Abstract】 The performance characteristics of tuned liquid damper( TLD) are studied in this paper and the results show that the damper has excellent capability of energy consumption. A model of 6 layers frame structure is constructed by ANSYS software,and the vertex maximum displacement responses are analyzed under severe earthquake. Meanwhile,the modal analysis is also completed. Based on the above,the modal distribution and location of the damage easily is obtained. Subsequently,the physical model is experimental tested on shaking table,and the results show that the TLD can effectively reduce the displacement and acceleration responses of frame structure. Among them,the vertex maximum displacement and the maximum acceleration is reduced by 38. 1% and 44. 0% respectively.更多还原
