摘要

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。

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.
