摘要
以Lagrange方程和龙格-库塔方法为基本方法,采用MATLAB编制求解程序,计算了在一个7层结构中设置双滑动面摩擦摆隔震系统的地震动力反应,并与未设置隔震系统的数值比较分析了双滑动面摩擦摆隔震系统的性能,分析与计算结果表明:结构基础设置双滑动面摩擦摆支座具有明显的隔震效果,当μ=0.01、r=3.5时隔震效果已达70%左右。
Based on Lagrange equation and Runge-Kutta method,using MATLAB to work out the program. Calculate the 7-layer structure ′s seismic response which have a double slipping-surfaced friction plate system,and compare the effect with no double slipping-surfaced friction. Result shows that equipped a double slipping-surfaced friction system at the foundation has a good seismic isolation effect. It could reach 70% for μ = 0. 01、r = 3. 5m.
