单峰式加速度反应谱规律性偏差统计研究

open access: yesDizhen xuebao
强震动记录显示,加速度反应谱普遍存在幅值大、宽度小的窄峰,这在现有地震动衰减关系(强震动预测方程)未能予以充分呈现。基于日本KiK-net台网近二十万条强震动记录,采用高斯曲线对单峰式加速度反应谱规律性偏差进行了拟合,利用高度、中心周期、宽度等三个参数对单峰式加速度反应谱规律性偏差予以参数化表征,分析了多个地震动、场地条件表征参数与这三个参数间的相关性,并据此建立了单峰式加速度反应谱规律性偏差的经验预测模型。分析结果表明,所建立的单峰式加速度反应谱规律性偏差经验预测模型 ...

基于KiK-net强震动记录的加速度反应谱规律性偏差

open access: yesDizhen xuebao
地震动特性受到地震震源、地震波传播介质和局部场地条件等因素的综合影响,虽然地震动反应谱虽然具有统计意义上的共性,但其具体形状又各不相同,特别是部分加速度反应谱与统计平均值之间存在显著的规律性偏差。为了进一步探究加速度反应谱与统计平均值之间的规律性偏差,本文基于日本KiK-net台网获取的8万余条强震动记录,建立了考虑地震震级和震中距影响的地面峰值加速度归一化加速度反应谱,并以预测值+0.5倍方差为界将加速度反应谱分为有、无反应谱规律性偏差的两组。通过有反应谱规律性偏差的反应谱(观测值 ...
