【摘要】 本文利用有限元法分析了铜管混凝土构件在轴拉力作用下的性能,讨论了钢管及内壁混凝土环向应力的变化情况,利用二维应力空间中的 Mises 屈服椭圆,明显地再现了铜管应力在弹性、弹塑性、塑性、强化及沿破坏面变化的路径。本方法将空心及实心轴拉构件的分析紧密地结合成一个有机的整体,为轴拉构件的分析开辟了一种崭新的方法。更多还原

【Abstract】 In this paper,the finite element method is used to analyze the behavior of concrete-filled steel tubular members subjected to axial tension.The stress variations of steel tube and internal wall of concrete are discussed.The stress changing course of steel tube was seen clearly in the elastic,elastoplastic and plastic stages by Von-Mises yielding criterion.This method closely con- neets the solid and the hollow members and opens a new way for the analysis of concrete-filled steel tubutar members subjected to axial tension.更多还原
