摘要
为研究绿色纤维对方钢管混凝土短柱受力性能的影响,通过ABAQUS对不同纤维体积掺量钢管混凝土短柱进行数值模拟分析,共设计3组试件,纤维掺入量分别为0%、1%、1.5%,通过观察不同掺量下构件的变形图以及荷载-位移曲线来研究绿色纤维对其构件力学性能的影响。结果表明绿色纤维对构件的横向变形影响较大,随着掺入量的增加,绿色纤维对构件的承载能力有明显提高,改善了构件的脆性和延性,并提高了整体构件的力学性能。
Steel tube concrete short columns with different fiber volume ratios are simulated by using ABAQUS to study the effectiveness of green fibers on the mechanical properties of square steel tube concrete short columns.Three sets of specimens with fiber additions of 0%,1%,and 1.5%are designed respectively.The influence of green fibers on the mechanical properties of the components is studied by observing the deformation diagrams and load dis-placement curves of the components under different fiber volume ratios.The results show that green fibers have a sig-nificant impact on the lateral deformation of the component.With the increase of the addition amount,the bearing ca-pacity of the component is significantly improved,the britleness and ductility of the component are improved,and the mechanical properties of the overall component are improved.
