摘要
本文采用ABAQUS有限元程序,对冷弯薄壁方钢管轻质混凝土短柱进行非线性有限元分析,计算和分析了冷弯薄壁方形钢管轻质混凝土短柱轴压时的荷载-位移全过程关系曲线。研究表明,设加劲肋能有效改善冷弯薄壁方钢管轻质混凝土短柱的承载能力。同时,研究了设肋方式、钢材强度、混凝土强度和钢管厚度对冷弯薄壁方钢管轻质混凝土短柱承载性能的影响。
In this paper,ABAOUS finite element program is used for non-linear finite element analysis of short lightweight concrete-filled square cold-formed thin-walled steel tubular columns to compute and analyze the complete loaddisplacement curve of short lightweight concrete-filled square cold-formed thin-walled steel tubular columns under axial compression.The results show that stiffening ribs can improve carrying capacity of short lightweight concrete-filled square cold-formed thin-walled steel tubular columns.Meanwhile,this paper studies effects of the set-up way of stiffening ribs,steel strength,concrete strength and thickness of steel tubes on load-carrying properties of short lightweight concrete- filled square cold-formed thin-walled steel tubular columns.
