Experimental investigations of tall/slender structure vibration control

塔被用作许多应用的最佳物理支撑。例如，它们能够安装大型电视、广播和移动通信平台。类似地，最常见的风力涡轮机塔的结构是由一个三叶片转子/齿轮/发电机系统组成，它位于一个高而细长的塔的顶部，通常由管状钢或预制混凝土建造。这些结构重量轻，具有很大的灵活性，并且对动力激励具有很高的灵敏度。因此，这些细长结构在风或地震等动力荷载作用下的结构安全性值得关注。通过使用多伦多大学研究团队实施的最先进的测试方法，并以行业合作伙伴的经验为基础，提出的研究将实验研究附加阻尼装置（即环形TLD）的动态行为，旨在减轻细长结构的振动。由此产生的实验数据库将有助于高效设计这种低成本、免维护的补充耗能装置，从而促进高层结构的安全、经济施工

Towers are used as the optimal physical supports for many applications. They enable, for example, the installation of large television, radio and mobile communication platforms. Similarly, the most common configuration of a wind turbine tower that harvests wind energy consists of a three-bladed rotor/gear/generator system sitting on top of a tall, slender tower typically constructed of tubular steel or precast concrete. These are lightweight structures with great flexibility, and are characterized by their high sensitivity to dynamic excitation. Thus there are concerns about the structural safety of these slender structures under dynamic loading such as that caused by wind or earthquakes. By using a state-of-the-art testing method implemented by University of Toronto research team, and building upon the experience of the industry partner, the proposed study will experimentally investigate the dynamic behaviour of a supplemental damping device (i.e., ring-shaped TLD) designed to mitigate the vibrations of slender structures. The resulting experimental data base will enable the efficient design of this cost-effective and maintenance-free supplemental energy dissipation device, which in turn will facilitate safe and economical construction of taller structures
