摘　　要：首先阐述了调谐液体阻尼器(TLD)的发展历程以及在实际工程中的应用,给出了TLD的基本数学模型,继而针对普通TLD晃动阻尼过小的问题,提出了在水箱中加设格栅板的改进措施。基于浅水理论,在MATLAB中对水箱的晃动数值求解。为了验证改进后的TLD较普通TLD的优势,利用OpenSees建立了一个9层钢结构模型,利用Client-Server技术实现OpenSees与MATLAB的耦合运算,对比普通TLD与设置格栅板TLD的减振效果,指出设置格栅板后TLD具有良好的、可调的减震效果。This paper first introduces the development of TLD and the application in the structure,and TLD’s mathematical model.Refering to the problem that TLD’s damping is too small,a improvement has been put forward in this paper,which adding a slat screen in the water tank.Based on shallow water theory,the liquid motion equation is solved by Staggered grid difference method and Runge-Kutta-Gill method.To test the performance of TLD with slat screen,a 9-Story Benchmark Building is modelled in OpenSees.Using the Client-Server technique,Matlab and OpenSees are coupled to calculate the response of Benchmark Building under several ground motions.
