【摘要】 基于5根圆钢管再生混凝土长柱试验,选取了合理的本构关系,利用大型通用有限元软件ABAQUS对圆钢管再生混凝土长柱进行了静力加载,并对比分析了模拟结果与试验结果。在此基础上对圆钢管再生混凝土长柱进行了参数分析,研究了长细比、取代率对圆钢管再生混凝土长柱受力性能的影响。结果表明,构件的承载力随着长细比的提高而降低,随着取代率的提高呈先提高后降低的趋势。更多还原

【Abstract】 Based on the five round steel tube recycled concrete long columns experiments, the reasonable constitutive relation was selected and the large general finite element software ABAQUS was used to load static force. The simulation result was compared with the test results. The parameter analysis of recycled concrete long round steel tube column was carried out to study the effect of the slenderness ratio and eccentricity on the mechanical properties of recycled concrete long columns round steel tube. The result shows that the bearing capacity of the component decreases with the increase of the length and slenderness ratio, and increases first and then decreases with the increase of the substitution rate.更多还原
