中文摘要目的研究外廊式钢筋混凝土框架的滞回曲线、耗能性能、延性、刚度退化等抗震性能.方法针对2008年汶川地震中某外廊式框架做ABAQUS拟静力分析,建立合理的有限元模型,对已有的试验结果进行对比及验证,并进一步分析该外廊式框架的抗震性能.结果试件在模拟的最后时刻,应力云纹均大量分布在柱子的顶端和底端,滞回曲线均较为饱满,峰值承载力具有对称性,最大承载力在150 kN左右,且与试验结果类似;骨架曲线也呈现出典型的纯框架特征,在达到极限承载力后平缓下降至最大承载力的85%;整体结构的刚度也在最后时刻下降到初始刚度的14%,耗能随着循环次数的增加而增加.结论该模型的有限元模拟的破坏位置与试验过程相类似;滞回曲线除了黏结滑移效应以外其他情况与实测情况具有较高的拟合度;骨架曲线表现出良好的延性,刚度也呈现出逐渐退化的特征,同时该结构具有较强的耗能能力.; This paper carries out a quasi-static analysis of a side corridor frame in the Wenchuan earthquake in 2008 with ABAQUS. A reasonable finite element is established and the FE results are compared with the existing experimental results to verify the FE model. Furthermore,the seismic performance of the side corridor frame is analyzed. The FE results showthat the stress cloud is mainly distributed at the top and bottom of the column at the final stage and the hysteretic curves are full with symmetrical peak capacity. The skeleton curve,stiffness degradation and energy dissipation also showtypical characteristics of a pure frame. In addition,the failure positions of the FE simulation are similar to the experimental process of the model. The hysteretic curve and actual situation match the experiment except the bond slip effect. The skeleton curve showsgood ductility and the stiffness also shows a gradual degradation. The skeleton curve also presents good energy dissipation capacity.
