| 中文摘要 | 以两个普通六层和十层钢筋混凝土框架结构为例,采用基于纤维模型的逐步增量弹塑性时程方法得到的层间剪力-位移关系曲线,与不同侧力模式的推覆分析结果进行了对比,研究了推覆分析结果的可靠程度。通过与不同场地的大量地震记录的弹塑性时程计算结果进行比较分析,建议采用多种合理的侧力模式进行推覆分析,对结构不同楼层的抗震性能进行全面的评价,即均布侧力模式适合于底部楼层的评价;考虑高度影响分布力模式适合于结构中部楼层的评价;而对结构上部楼层特别是顶层,可以采用SRSS侧力模式或规范侧力模式进行评价。分析研究表明,采用本文建议的侧力模式进行推覆分析,可在统计意义上可对钢筋混凝土规则框架结构的抗震能力作出偏于安全的估计。; In this research,the nonlinear static procedures with different lateral load patterns were compared by using incremental dynamical analysis method based on a six-storey and a ten-storey RC frame fiber model.For each story of different frames,the inter-story shear force vs.drift curves computed by pushover analysis by using different lateral load patterns and time history analysis with a series of earthquake records on the design site have been compared to give a rational lateral load pattern of pushover analysis.Finally,for a whole frame structure,the lateral load pattern choice was suggested,that is,uniform load pattern was better for the stories near foundation;load pattern with the story heights taken into consideration was suitable for the mid stories and the SRSS pattern or Chinese Code pattern was suitable for upper stories.It is also shown that the nonlinear static procedure gives a safe estimation of the inelastic seismic response statistically for regular RC frames with good numerical stability. |
