摘要
本文应用矩阵传递法分析了具有被动调谐质量阻尼器(P-TMD)系统控制的电视塔结构地震反应,优化了TMD系统的各参数(包括质量比μ、固有频率ω_d和阻尼比ζ_d等),对TMD系统在结构上的安装位置提供最佳选择。并实例分析了一座380m高的电视塔结构,说明控制后能够显著地降低其地震反应。
In this paper, seismic responses of TV tower structure under the control of Passive Tuned Mass Damper ( P-TMD ) system are analyzed by the matrix transfer method. In which, th 'parameters (including mass ratio μ, natural frequency ωδ and damping ratio ξd) of the TMD system are optimized and the positions of TMD on the structure chosen. The analysis of a TV tower structure 380m in height shows that the seismic responses of the tower controlled by the TMD system can be decreased significantly.
