| 摘 要： | 在确定钢管与核心再生混凝土本构关系模型的基础上,采用有限元法对钢管再生混凝土轴压短柱、纯弯构件和压弯构件的破坏模态和荷载-变形关系曲线进行全过程分析,揭示出受力过程中钢管与核心再生混凝土截面应力分布规律及钢管与核心再生混凝土之间的相互作用,较为深入地认识了静力荷载作用下钢管再生混凝土构件的工作机理。

| Abstract: | Based on the constitutive models of steel and core recycled aggregate concrete(RAC),the failure modes and the load versus deformation complete curves of recycled aggregate concrete filled steel tubular(RACFST) stub columns,beams and beam-columns were calculated using finite element analysis(FEA) method. The analytical results reveal the rules of stress distribution in steel and RAC cross-section,and the interaction between the steel tube and core RAC under loading procedure.The results in this paper deeply demonstrate the working mechanisms of RACFST members subjected to static loads. |
