摘要:
在17个钢筋钢纤维混凝土牛腿试件试验的基础上,采用非线性有限元方法探讨钢纤维体积率、剪跨比和混凝土强度对钢筋钢纤维混凝土牛腿抗裂性能的影响.结果表明,掺入钢纤维后,钢筋混凝土牛腿的正截面抗裂荷载可提高10%左右;随着混凝土强度增加,钢筋钢纤维混凝土牛腿的正截面抗裂荷载线性提高;但是,随着剪跨比增加,钢筋钢纤维混凝土牛腿的正截面抗裂荷载明显降低.并且通过数值模拟分析结果和试验结果的对比,验证了有限元分析模型中所采用的单元类型、材料本构关系及破坏准则的合理性,为实际应用提供相应的参考.
Abstract:
Based on the experimental results ot 1 7 steeI fiber reinforced concrete corbels，the numericaI simu。lation with nonlinear finite element method was adopted to analyze the behavior and to explore the influence ofsteel fiber volume ratio，the shear span ratio and the strength of concrete on cracking—resistance behavior ofsteel fiber reinforced concrete corbels．The result shows that the cracking—resistance behavior increases about1 0 percent with the increase of the volume ratio of steel fibers，and the cracking—resistance behavior increaseslinearly with concrete strength，but the cracking—resistance behavior decreases markedly with the increase ofshear span ratio．By contrasting the numer／cal simulation analysis results with the expe6ments，it proves therationality of the unit type，material stress—strain relations and failure criteria used in the finite element analy—sis model．Therefore，it provides a reference for practical usage．
