Abstract

Based on the principle of dynamics of structures and fluid mechanics,the vibration reduction principle and the calculation formula of tuned liquid and mass damper (TLMD) were deduced,and the design method of TLMD was summarized.By combining the finite element model of TMD with the free vibration test of the single freedom system,the feasibility and accuracy of the TLMD design method were tested.Experimental results show that the damping effect of TLMD is in good agreement with the simulation results,and the vibration suppression effect of TLMD was approximate to the superposition effect of TLD and TMD.The design process is simple also.Eventually,taking a 30-story steel structure building for example,the design process of seismic damping by TLMD was demonstrated.
