多质点隔震结构数值分析和试验研究
|
摘要
运用数值分析的方法,对隔震和非隔震质点系简化模型的周期进行对比,并利用近似解法的Matlab程序进行验证,指出隔震技术可以延长结构的基本周期,降低建筑物地震响应;近似解方法有很高的精确度,不仅在数值上能够满足一定的精度范围,而且计算简单方便,可以用于对结构周期进行预估。
This paper uses the numerical analysis method to compare with the period of isolation and non-isolation particle system model,and writes Matlab program of approximate solution to prove. It points out that the isolation structure can extend basic period and reduce the seismic response of the buildings. The approximate solution has high precision,not only does it can meet the precision range in value,but also the calculation is simple and convenient. We can use the approximate solution to estimate the period of the structure.
