| 摘 要： | 基于现行的抗震设计规范设计了三层、六层和九层的钢筋混凝土平面框架结构.并对这些钢筋混凝土框架结构在近场脉冲型地震动和一般地震动作用下的动力响应进行了研究,研究发现:对于近断层地震的脉冲效应现行的抗震设计规范考虑不充分,结构的层间位移角并不能满足1/50的限制条件.因此建议不考虑地震调整系数,以此来保证结构在近断层地震作用下的安全.

| Abstract: | Based on the existing design code,three-story,six-story and nine-story rein forced-concrete framed structures are designed.Seismic response of these reinf orced-concrete framed structures subjected to near-fault pulse-like ground mo tions and ordinary ground motions is investigated.It is shown through numerical results that consideration on the effect of near-fault pulse-like ground moti ons on the structures is not adequate and the story-drift will be greater than the limit of 2%.Therefore,it is suggested ... |
