摘要
本文采用调谐质量阻尼器对地王大厦这一高层建筑在风荷载作用下的顶点位移进行主被动混合控制,即50a重现期风荷载作用下用TMD被动控制,100a重现期风荷载作用下切换为TMD主动控制。理论分析和计算表明,这种控制方式造价低,经济效果佳,以较小的能量输入可取得较优的控制效果。
Against the background of one large scale high-rise steel structure--Diwang Tower, located in (Shenzhen) City, A hybrid mass damper system (HMD) with convertible active and passive modes against strong wind is studied. After extensive parametric studies in frequency domain and time domain, the optimal design parameters of hybrid mass damper system are determined. The theoretical analysis and simulation results show that HMD can take advantage of passive mass damper and active mass damper, is an efficient and cheap control system.
