【摘要】 基于30组近场地震记录,研究了近场地震竖向效应对结构位移的影响。对6层和10层框架结构算例分别输入每一组近场地震记录进行动力时程分析,时程分析统计结果表明,近场地震竖向效应对框架结构楼层及层间位移具有明显的增大作用,必须引起地震工程界研究、设计人员的高度重视。更多还原

【Abstract】 Based on 30 sets of acceleration records of near-fault earthquake,the influence of vertical effect of near-fault earthquake on displacement demand of structures was studied.Using each set of near-fault acceleration records,a set of dynamic time-history analyses was carried out to determine the displacement responses of 6 story and 10 story frames,the statistical results show that the vertical effect of near-fault earthquake will remarkably amplify the floor displacement and the inter-story drift demands of frame structures,to which much attention should be paid by the researchers and designers in the field of earthquake engineering.更多还原
