摘要
风对结构的作用就是一种能量的传递、转化与耗散过程,当风输入到结构的能量(输入能)小于结构的耗能能力时,结构是安全的,反之结构将会破坏。本文以主结构的阻尼耗散能为目标函数,采用全结构最优分布原理对分布于76层Benchmark模型上的阻尼器位置和参数进行优化设计,并对比分析其结果;其次,将TMD和阻尼器联合起来控制,并与单独设置TMD或单独设置阻尼器的单一控制方式进行比较,证明了混合控制的优越性。
The effect of wind on the structure is a kind of energy changing process, which can be transmitted, transformed and dissipated. Whether the structure will be safe or not is completely depended on the energy - dissipating capacity. In this paper, a 76 - store Benchmark model is established based on the energy principle. With the mean of optimal method, the passive controllers installed in 76 - store Benchmark model are optimally designed. Then, taking TMD and dampers （Hybrid control system） into account, it is advisable for us to select the Hybrid control system more than the TMD system and the damper system.
