摘要
为实现钢-混凝土组合简支梁滞回性能三维非线性有限元分析,该文提出混凝土在单轴拉、压应力下的损伤变量计算方法,给定了混凝土的卸载规则,完善并提出混凝土应力-应变滞回本构关系和钢材循环本构关系,应用ABAQUS有限元软件建立混凝土棱柱体试件、钢材试件和钢-混凝土组合简支梁有限元三维非线性有限元模型,对混凝土棱柱体试件在单轴受压和受拉反复荷载下的试验结果进行分析,对钢材试件在单轴拉压循环荷载下的试验结果进行分析,对钢-混凝土组合简支梁在循环荷载下的荷载-挠度滞回关系、梁端荷载-滑移滞回关系以及栓钉的荷载-侧向变形滞回关系曲线等试验结果进行分析,计算结果与试验结果符合较好。
This paper presents a 3D nonlinear finite element method to analyze hysteresis behavior of simply supported steel-concrete composite beam under low cyclic reverse loading.The calculation method for damage variables of concrete under unixial load was proposed,the unloading rule of concrete was given,and the hysteretic stress-strain relationship of concrete and the cyclic constitutive model of steel were constructed.Finite element models of prism specimens of concrete,specimens of steel and simply supported steel-concrete composite beam were established through ABAQUS.The test results of hysteretic stress-strain relationship of prism specimens of concrete under unixial cyclic loading of compression or tension,hysteretic stress-strain relationship of specimens of steel under unixial cyclic loading of tension and compression,and the hysteretic load-deflection relationship of the simply supported steel-concrete composite beam,hysteretic load-slip relations of beam end and hysteretic load-lateral deformation curves of stud were analyzed,the analysis results are in good agreement with the experiment results from references.
