橡胶支座地下室顶板与基础顶面隔震对比

Comparative Study of Rubber Bearing on Basement Roof and Isolation Effect of Top Surface Basis

在简化模型的基础之上,根据拉格朗日方程推导出橡胶支座地下室顶板隔震动力反应的计算公式。利用MATLAB软件进行数据处理,并结合ORIGIN软件把数据以图像的形式简单明了地表现出来,为更加细化的数据比较分析打下了扎实的基础。结果表明:把橡胶支座设置在地下室顶板与无隔震支座相比具有明显的隔震效果,当Cr=3 000kN/(m·s),kr=2 000kN/m时,隔震效果保持在90%以上,甚至达到96.56%。

Based on the simplified model and combined with the Lagrange Equation,this paper derived a calculation formula.This calculation formula is about dynamic response for isolation effect of rubber bearings on the basement roof.Data were analyzed by the MATLAB software and simply performed by the ORIGIN software,which laid a solid foundation for more detailed comparative analysis of the data.Analysis and calculation results show that:the roof of the basement which is arranged with the rubber bearing has better isolation effect compared with those have no bearings.When Cr= 3000kN/ms,kr= 2 000kN/m,the isolation effect is maintained at 90% or more,even up to 96.56%.
