| 摘 要： | 为研究近断层地震作用下基于位移的抗震设计方法,选择了30次地震,132组近断层地震记录作为统计样本,根据得到的平均弹性位移反应谱,给出了近断层地震设计弹性位移反应谱表达式,该表达式可以反映震源机制和场地土等因素的影响作用.研究结果表明:提出的近断层地震弹性位移设计反应谱与实际地震波平均弹性位移反应谱较为接近,可以应用于近断层地震作用下结构的抗震设计中.

| Abstract: | In order to study displacement based seismic design method of near fault ground motions, 30 earthquakes and 132 near fault ground motion records were selected as statistical samples. The elastic displacement response spectra formula of near fault ground motions was proposed from the statistical average elastic displacement response spectra. The response spectra formula can reflect the effect of focal mechanism and ground soil. It can be concluded that the elastic displacement design response spectra of near fault ground motions proposed in the paper is close to the average elastic displacement response spectra of actual earthquake waves, and it can be applied in seismic design of structures subject to near fault ground motions. |
