【摘要】：由于金属阻尼器具有滞回特性稳定、耗能能力良好、构造简单、造价低廉、对环境和温度的适应性强以及维护方便等优点,已被广泛应用于实际建筑结构的振动控制中。以某学校食堂的金属阻尼器减震设计为例,介绍了金属阻尼器减震结构的设计分析方法,并对结构进行了大震下的弹塑性时程分析,对比了减震与非减震结构在大震作用下的性能。分析结果表明,除顶层以外,采用了金属阻尼器的减震结构在大震作用下的层间位移角较小,且能够满足大震不倒的要求。此外,分析了减震结构顶层层间位移角增大的原因,并指出了在布置阻尼器时必须遵循均匀、分散、对称的布置原则。
[Abstract]:Metal dampers have been widely used in vibration control of building structures because of their advantages of stable hysteretic characteristics, good energy dissipation, simple construction, low cost, strong adaptability to environment and temperature, and convenient maintenance. Taking the design of metal damper in a school dining hall as an example, the design and analysis method of metal damper structure is introduced, and the elastic-plastic time-history analysis of the structure under the strong earthquake is carried out. The performance of shock-absorbing and non-shock-absorbing structures under the action of large earthquakes is compared. The results show that, except for the top layer, the interstory displacement angle of the structure with metal dampers is small under the action of large earthquakes, and it can meet the requirements of large earthquakes. In addition, the reasons for the increase of the displacement angle between the top floors of the shock absorption structure are analyzed, and the principle of uniform, dispersed and symmetrical arrangement of dampers is pointed out.
