场地类型对反应谱平台值的影响
|
摘要
文中在总结一些学者研究基础上,利用土层地震反应分析的一维等效线性化波动方法,以建筑抗震设计规范规定的反应谱为目标谱,合成不同加速度峰值和特征周期加速度时程曲线共28条,将其作为土层地震反应分析的输入地震动,选取和构造了四种场地类型的225个土层剖面,计算了不同土层剖面在不同地震动输入下的设计反应谱的平台值。基于统计分析,给出了不同场地反应谱平台值的平均值;基于一元线性回归分析,给出了不同场地反应谱平台值与输入地震动强度的关系式。
On the basis of the summary by some scholars,by using the 1-D equivalent linearization wave motion method,and by taking the specified response spectrum in the code for seismic design of buildings as target spectrum,28 acceleration histories with different acceleration peaks and characteristic periods were formed artificially.They will be used as the ground motion inputs in ground response analysis.225 site profiles of four types of sites were selected or constructed,the flat section values of design response spectra for different profiles under different ground motion inputs were calculated.On the basis of statistical analysis,the average flat section values of response spectra of different types of sites were gained.By using the linear regression,the relationships between the flat section values of response spectra for different types of sites and input ground motions were established.
