(1)为了有效控制瞬态响应，提出了带初始位移的半主动调谐质量阻尼器。对其基本特性进行了分析研究，提出了最优初始位移及其他设计参数的设计公式。(2)分析验证了该系统对冲击荷载作用下大跨度屋盖结构的振动控制效果。(3)建立了具有初始位移的调谐质量阻尼器的实验模型，并用平板模型实验验证了振动控制的效果。

(1) To effectively control transient response, we propose semi-active tuned mass dampers with initial displacement. We analytically studied about the basic characteristics and proposed design formulas for the optimal initial displacement and other design parameters. (2) We analytically confirmed the effect of vibration control of the proposed system for a large-span roof structure under an impulse load. (3) We made an experimental model of the tuned mass damper with initial displacement and experimentally confirmed the effect of vibration control with a plate model.
