Experimental Study and Numerical Simulation on the Components of a Functionally Separated Energy Dissipation Bearing
在减震球型钢支座的基础上,本文提出了一种新型功能分离型自复位耗能支座,其减震耗能组件由耗能钢元件与钢板弹簧元件以类似系杆拱的形式组成。本文采取试验与数值模拟相结合的研究方法分析其减震机理和减震效果,设计进行了耗能元件LYP100钢材的材料性能试验、板簧元件的刚度性能试验,同时对减震耗能组件进行了拟静力加载试验和数值模拟研究。研究结果表明:LYP100钢材滞回曲线饱满,耗能性能优良;钢板弹簧在横向荷载作用下工作性能稳定,可以为减震耗能组件提供稳定的刚度;在工作过程中,板簧元件始终保持弹性状态,实现了支座的自复位功能,耗能元件在加载初期就进入塑性状态,实现了塑性耗能。
On the basis of the damping spherical steel bearing, a new type of functionally separatied self-centering energy dissipation bearing is proposed. The energy dissipation steel element and the plate spring element form the damping energy dissipation component in the form of similar tied arch. In this paper, the research method of combining test and numerical simulation is adopted to analyze the damping mechanism and damping effect. The LYP100 steel material performance test of energy dissipation element and the stiffness performance test of plate spring element are designed and carried out. At the same time, the quasi-static loading test and numerical simulation of the damping energy dissipation component are carried out. The results show that the hysteresis curve of LYP100 steel is full and the energy dissipation capacity is excellent. The plate spring has stable working performance under lateral load, which can provide stable stiffness for energy dissipation components. During the working process, the plate spring element always maintains the elastic state and realizes the self-centering function of the bearing. The energy dissipation element enters the plastic state at the initial stage of loading and realizes the plastic energy dissipation.
