为进一步深化现有波纹钢腹板组合箱梁桥应力集中效应研究理论,优化现有工程设计,以某波纹钢腹板组合箱梁桥为工程背景建立节段空间有限元模型,分别对腹板与顶底板倾角、波纹钢腹板尺寸参数等进行分析。通过多组设计参数,研究应力集中变化情况,找出不同设计参数对应力集中的影响规律,并进行相应的敏感性分析。
In order to further deepen the research theory of stress concentration effect of the existing corrugated steel web composite box girder bridge and optimize the existing engineering design, a finite element model of segment space is established with a corrugated steel web composite box girder bridge as the engineering background, And the top floor dip, corrugated steel web size parameters for analysis. Through several sets of design parameters, the change of stress concentration is studied, the influence laws of different design parameters on stress concentration are found, and the corresponding sensitivity analysis is carried out.
