摘要
基于数值模拟验证试验正确性基础上,本文采用有限元软件ABAQUS建立6个分析模型,研究了双不锈钢板混凝土组合梁中抗剪钢筋直径和间距对双不锈钢板混凝土组合梁抗剪承载力影响.结果表明,增大抗剪钢筋直径和缩小间距均可提升试件的极限抗剪承载力,且提升幅度与抗剪配筋率(与直径、间距相关)成正比.该分析结果为后续系统全面地开展双不锈钢板混凝土组合梁参数分析提供参考.
On the basis of numerical simulation to verify the correctness of the test,this paper establishes six analysis models by using the finite element software ABAQUS to study the influence of the diameter and spacing of shear reinforcement on the shear capacity of double stainless steel plate concrete composite beams.The results show that increasing the diameter of shear reinforcement and reducing the spacing can improve the ultimate shear capacity of the specimens,And the lifting range is directly proportional to the shear reinforcement ratio(related to diameter and spacing).The analysis results provide a reference for further systematic and comprehensive parameter analysis of concrete composite beams with double stainless steel plates.
