组合基础隔震结构能量反应分析
|
摘要
对组合基础隔震结构进行了能量反应分析,研究了地震波峰值、上部结构基本周期、组合基础隔震结构基本周期对结构总输入能量的影响,并对结构进行了耗能分析,结果表明随着地震波峰值的增大,结构的总输入能量增大;上部结构基本周期对结构总输入能量影响较小;随着基础隔震结构基本周期的增大,结构的总输入能量减小;组合基础隔震结构总输入能量的90%左右被组合隔震系统耗散.
The analysis on energy response of the combined base-isolated structures is carried out.The effects of the peak value of the ground motions,the fundamental periods of the superstructures and the base-isolated structures on the total input energy are studied,then the energy dissipation is analyzed.As the peak value of the ground motions increasing,the total input energy of the structure will increase.The fundamental periods of the superstructures have less effect on the the total input energy of the structure.As the fundamental periods of the base-isolated structures increasing,the total input energy of the structure will decrease.The 90 percent of the total input energy of the structure is dissipated by the combined isolation system.
