摘要
在继效流动理论的基础上，对长期荷载作用下钢管混凝土的轴心受压徐变进行了分析。针对钢管混凝土受力的特点，对计算模型进行简化，提出了一维的钢管混凝土徐变计算公式，与文献［５］中基于试验回归得到的徐变计算公式进行比较。
Based on the theory of Elastic Continuation and Plastic Flow for concrete creep, the paper derives a formula to calculate the creep of Concrete Filled Steel Tubular(CFST) members under axial loading, which can rationally render the creep mechanism of CFST members. The results calculated by the method agree well with experimental data, verifing the proposed method.
