【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.更多还原

【Abstract】 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.更多还原
