摘要
根据“统一”理论推断 ,对不同截面形式的钢管混凝土轴压短柱采用有限元方法进行分析 ,得到了圆形、方形、矩形和八边形截面轴压短柱的平均应力 -应变全过程关系曲线。最后导得各种截面钢管混凝土轴压短柱的组合性能指标及承载力设计公式。研究结果表明 ,各种截面形式的钢管混凝土的性能变化是连续的。
According to the Unified Theory,the concrete-filled steel tube(CFST)columns with different sections subjected to axial compression are analyzed by FEM,whose mean stress-strain curves are also obtained. The results of analysis shows that the changes in behaviors for various forms of CFST members are continuous. And the composite strength standard and design values for various forms are given.
