摘要

以千余条水平分量地震动记录为数据基础,考虑场地条件,距离和震级的影响,对地震动的加速度规准反应谱和双规准反应谱进行了研究.规准反应谱明显受到场地条件,距离和震级的影响,但场地、距离和震级影响下的平均双规准谱之间却表现出良好的一致性,基于此建议了统一的双规准设计谱模型.考虑阻尼比的影响和与现行规范设计谱的衔接,建议了可供工程设计参考使用的抗震设计谱,并与现行规范设计谱进行了比较.
Normalized response spectra(NRS) and bi-normalized response spectra(BNRS) were investigated.Considering the influence of site condition,distance and magnitude.Around 1000 horizontal acceleration components of strong motion recordings were introduced to the analysis.Result of the analysis indicated that site condition,distance and magnitude obvariously influenced NRS,while slightly affected BNRS.A uniform bi-normalized design spectrum model was proposed based on consistency features of BNRS.Considering the influence of damping ratio and the results used in current provisions,seismic design spectra are then constructed and compared with design spectra of code provisions.
