摘 要:不锈钢管混凝土(CFSST)结构在工程的应用愈发广泛,但目前对其轴压性能的研究较少。该文利用ABAQUS创建方形不锈钢管混凝土短柱(CFSSST)模型,并利用收集到试验结果对其进行验证。采用已被验证的模型进行参数分析,研究截面宽厚比和混凝土强度对其轴心受压性能的影响,并将参数分析轴压承载力结果与GB 50936—2014《钢管混凝土结构技术规范》、欧洲规范EN 1994-1-1和美国钢结构规范AISC 360-16中钢管混凝土(CFST)短柱轴压承载力的计算值进行对比,结果表明:规范的计算值偏于保守。最后,基于GB 50936—2014《钢管混凝土结构技术规范》提出适用于CFSSST短柱轴压承载力的计算公式,收集到的试验结果与计算值吻合良好。Concrete-filled stainless steel tube structures is widely used in engineering practice,however,the research on its axial compression performance is limited.In this paper,the compressive behavior of CFSSST stub columns has been investigated.The finite element(FE)software ABAQUS was to used to establish the FE analysis.Based on the experiments results,the validity of the FE model was verified.The influence of widththickness ratio of the section and concrete strength on the compressive behavior of CFSSST stub columns was investigate by using the FE model,and parametric analysis results,which were compared with predicted load values by codes GB 50936—2014,EN 1994-1-1 and AISC 360-16,indicate that the predicted load values are the conservative.Finally,based on the code GB 50936—2014,the calculation formula for the ultimate capacity of CFSSST stub columns is proposed.Predicted values using the calculation formula agree well with the collected test results.
