| 摘 要： | 文章对比研究了钢管混凝土(CFST)和钢管再生混凝土(RCFST)框架体系抗震性能。通过建立CFST和RCFST框架体系有限元模型,分别对两种模型进行了模态和动力时程分析。分析结果表明:RCFST与CFST框架体系相比,整体刚度减小,自振周期变大;在多遇和罕遇地震作用下,RCFST相比CFST框架体系顶层位移和层间位移角增幅不大,而基底剪力减小;通过对比分析认为RCFST框架体系在地震作用下抗震性能良好。

| Abstract: | In this paper, the seismic performance of concrete filled steel tube (CFST) and recycled concrete filled steel tube (RCFST) frame system was compared. First, the finite element models of CFST and RCFST frame system were established, then modal and dynamic time-history analysis on the two models was conducted. The analysis results indicate that compared with CFST frame system, the stiffness of RCFST frame system declines, and natural vibration period increases; under the influence of frequent earthquake and rare earthquake, the increase of RCFST frame system''stop floor displacement and that or the story drift are not large compared to those of CFST frame system, while its base shear decreases; through contrastive analysis, it is held that RCFST frame system has good seismic performance. |
