摘要
在确定组成矩形钢管混凝土的钢材和核心混凝土应力应变关系模型的基础上,利用数值解法对矩形中空夹层钢管混凝土轴压构件的荷载-变形关系进行了全过程分析.
Utilizing the stress-strain relations of steel and concrete presented in the literature for concrete filled rectangular steel tubes, a numerical method is applied for the analysis of load-deformation curves of the double-skin composite members subjected to axial loading.
