【摘要】 结构被动控制技术将传统的依靠结构自身强度和刚度来增强结构抗力的设计方法转变为利用控制装置吸收并耗散振动能量,是抗震防灾的一种积极有效的设计手段。基于被动控制机理,分别从隔震、消能减震和调谐减震3种途径系统总结了被动控制技术在大跨空间结构中的应用概况,介绍了相应的控制措施和控制效果,给出了实用性的结论,结果可为大跨空间结构的工程设计提供参考。本成果对推动振动控制手段在大跨空间结构中的实际应用具有积极意义。更多还原

【Abstract】 Passive control technology is an effective method for earthquake disaster prevention of structures.It Absorbs and dissipates vibration energy of structures by using control devices,which is quite different from traditional ways of strengthening the structural resistance by its own strength and stiffness.In this paper,present situation on application of the passive control technology in long-span spatial structures is summarized according to seismic isolation,energy dissipation and tuned vibration reduction,respectively.The related control measures and control performance are also introduced.Practical conclusions are made.The information given in this paper will provide good references for practical design of the long-span spatial structures and further promotes the development of control technology in the structures.更多还原
