含软弱土层场地地震动加速度反应谱特征周期调整方法

open access: yesDizhen xuebao
在分析场地条件对地震震害影响及国内外关于软弱土层对场地地震反应影响的基础上,采用实际含淤泥质土层场地资料,建立了12个含软弱土层的场地模型,在不同输入地震动水平下进行了场地地震反应一维等效线性化分析,讨论了软弱土层厚度和埋深对场地地震反应的影响。结果表明:随着软弱土层的埋深或厚度的增加,反应谱特征周期逐渐增大;输入地震动峰值增加,反应谱特征周期亦增大。继而依据软弱土层厚度、埋深及输入地震动强度对场地加速度反应谱特征周期的影响特征,提出了含软弱土层场地地震动加速度反应谱特征周期调整方法。

Hospitalization Through Families’ Eyes: Comparing Inpatient Care Quality for Children With Sickle Cell Disease and Cystic Fibrosis in Canada

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...
