摘要
建立了滑移隔震结构的计算模型并引入新的研究参数,从能量的角度研究了滑移隔震结构在地震作用下的能量耗散规律,采用数值分析的方法对比分析了滑移隔震结构在不同地震波作用下结构设计参数对上部结构和隔震层阻尼耗能的影响规律,结果表明,上部结构的阻尼耗能考虑与否与上部结构的基本周期有关,而隔震层的阻尼耗能可以不考虑.
Calculation model of sliding base-isolated structure was built and the new parameters were introduced,the laws of energy-dissipation of sliding base-isolated systems of building structures under the earthquake effect were studied from the angle of energy, the influence laws which structure design parameters on the damping energy-dissipation of superstructure and isolation layer under the action of different seismic waves were contrasted and analyzed using the numerical analysis methods. The results show that if the damping energy-dissipation of superstructure is considered or not is related to the basic cycle of superstructure, while the damping energy-dissipation of isolation layer can not be considered.
