Parameters study of rural buildings structures supported on slide-limited friction base isolation system

针对村镇建筑带限位装置摩擦隔震技术,建立了隔震装置的综合恢复力模型和隔震体系的运动方程,编制了考虑摩擦效应的非线性分析程序,详细分析了隔震层摩擦系数、限位装置弹性刚度和屈服位移等因素对隔震体系的影响,最终通过大量计算给出了参数选取的合理取值范围,可为该隔震体系的简化设计和实际应用提供依据。

Regarding the slide-limited friction base isolation technology,the total restoring force model of isolation device was provided,the motion equation of isolation system was established,and the nonlinear analysis program was worked out.The influencial factors such as friction coefficient,elastic stiffness and yield displacement of displacement-constraint device on base isolation system were analyzed in detail,and based on a great deal of analysis,the rational ranges of the parameters were given out,which can provide reference for design and application of the friction base isolation system.
