摘　　要：近年来组合隔震体系在工程抗震领域应用日益增多。本文基于组合隔震技术将滑板隔震支座的摩擦滑移元件和叠层橡胶隔震支座的橡胶元件并联形成一种新型隔震支座——自复位刚性滑板隔震支座。通过试验研究不同压力、加载位移及水平加载频率与滞回特性的相关性等性能,基于ABAQUS有限元软件对该支座进行数值模拟分析。研究结果表明:数值模拟结果与试验结果吻合较好;自复位刚性滑板隔震支座具有更高的竖向承载力,支座滞回曲线稳定饱满,拥有良好的隔震效能,是一种可适用于工程应用的隔震支座。In recent years,the application of combined seismic isolation system in engineering seismic field is increasing.Based on the combined isolation technology,the friction sliding element of the sliding plate isolation bearing and the rubber element of the laminated rubber isolation bearing are paralleled to form a new type of isolation bearing-self-centering rigid sliding plate isolation bearing.Through the experimental study of different pressure,loading displacement and horizontal loading frequency and hysteresis characteristics of the correlation,the numerical simulation analysis of the bearing is carried cut by using ABAQUS finite element software.The results show that the numerical simulation results are in good agreement with the experimental results.The self-centering rigid sliding plate isolation bearing has higher vertical bearing capacity.The hysteresis curve of the bearing is stable and full,and it has good isolation performance.It is a kind of isolation bearing suitable for engineering application.
