【摘要】 对轴心受压方中空夹层钢管混凝土的荷载-变形关系曲线进行了数值计算.在此基础上,本文借用方钢管混凝土轴压强度承载力的简化计算公式对方中空夹层钢管混凝土进行计算,该方法简单实用,且简化计算结果与数值计算结果和试验结果均吻合较好.更多还原

【Abstract】 Load-deformation relations of Concrete Filled Double Skin Steel Tubes (CFDST) subjected to axial compressive load are analyzed in this paper.Then the CFDST section capacity are calculated by the simplified formulas for Conc(?)et Filled Steel Tubes(CFST).This method is simple and practical,and the calculated re- suits of the formulas show reasonable agreements with those of tests and those of calculated.更多还原
