Key Words:钢管混凝土柱; 承载力; 破坏过程; 非均匀性

Abstract:采用RFPA~(3D)(Realistic Failure Process
   Analysis)软件对轴心受压的矩形钢管混凝土短柱进行了数值模拟.分析了极限承载力与钢管混凝土柱长度的关系以及混凝土截面面积对极限承载力的影响
   等问题.研究结果表明,钢管混凝土柱的极限承载力随着柱长度的增加而降低,随着截面面积的增加而增加.在钢管混凝土承载力方面,数值模拟结果与试验结果比
   较吻合.数值模拟的特色在于再现了核心混凝土的变形、损伤与破坏过程.数值模拟结果证明了RFPA~(3D)软件模拟钢管混凝土结构的有效性,其模拟结果
   可为工程设计提供参考.
