摘要:
为控制结构侧向变形和震后残余变形, 提出一种具有复位功能的阻尼耗能支撑, 该支撑采用组合碟簧提供复位力, 永久磁铁产生恒定磁场, 利用磁流变液的流变性能耗散地震输入能量.在复位系统和耗能系统滞回模型基础上, 建立了描述支撑滞回特性的恢复力模型, 并对其磁路及滞回性能进行了模拟分析.结果表明, 新型阻尼耗能支撑具有稳定饱满的旗形滞回特性, 复位性能良好, 可提供必要的抗侧刚度和复位力以减小结构层间位移及震后残余变形, 其耗能能力随着加载速率增大而增强, 所建立的恢复力模型可以精确描述支撑的滞回特性.
Abstract:
In this paper,an innovative damping energy dissipation brace with self-centering capability is developed to control the lateral drift and residual deformation of structures during earthquakes. The self-centering force of brace is provided by the combination disc springs,the constant magnetic field is produced by a permanent magnet,and the rheological properties of magnetorheological(MR)fluid are used to dissipate the input energy of earthquakes. Based on the hysteretic model of self-centering system and energy dissipation system,a restoring force model is established to portray the hysteretic behavior of the brace,and the magnetic circuit and seismic performance of brace are simulated. Results indicate that the innovative damping energy dissipation brace exhibits stable and full flag-shaped hysteretic behavior and excellent self-centering capability,which can provide necessary lateral stiffness and restoring force to reduce the lateral drift and residual deformation of structure after earthquakes,and the energy dissipation ability of the brace is enhanced with the increase of loading rate,and the hysteretic behavior of this brace can be accurately portrayed by the proposed restoring force model.
