摘　　要：提出一种新的控制策略——复合多重调频质量阻尼器(CMTMD).将钢结构建筑简化为多自由度体系计算模型,利用复模态理论推导出在高耸钢结构建筑的不同层上安装MTMD后,在风荷载作用下的随机响应.实例计算结果表明:CMTMD具有优于传统MTMD的控制效果.A new control strategy in complex multiple tuned mass dampers for high-rise structures is studied in the paper. Based on the complex mode analysis theory of random vibration, simplifying the controlled structure as a multi-degree of freedom structural system, this paper studies the location of MTMD on the high-rise TV towers and derives vibration displacement response spectrum. The results of theoretically analyzing and calculation show that CMTMD has many advantages such as efficiency, robustness and so on, compared with MTMD.
