| 摘 要： | 结构在近场地震动作用下的反应和远场地震动作用下的明显不同，这主要是由近场地震动高能量的速度脉冲等特征决定的。通过对110条近场地震动记录的分析．得到了相应的弹性反应谱，并通过对近场地震动和远场地震动作用下结构塑性分析进行对比．得到了以下结论：近场地震动作用下结构的弹性反应谱与规范谱明显不同，尤其在长周期阶段，表明规范谱值偏小；近场地震动作用对结构提出了更高的强度和变形需求。

| Abstract: | Near-field earthquakes result in quite different structural responses from far-field earthquakes, which is mainly due to the characteristic of high-power velocity pulses for near-field earthquakes. In this paper, elastic and inelastic response spectra are obtained based on the analysis of 110 near-field ground motion records. Comparison of response spectra for near-field and far-field earthquakes is conducted and the results show that the near-field earthquake has a distinct response spectrum compared to the design spectrum, especially in the long-period range. The near-field earthquake shows much higher demand of strength and deformation. |
