摘要

摘要: 为了简化波形钢腹板组合箱梁的三维有限元建模过程，通过刚度和位移等效的方法将三维波形钢腹板有限元模型简化为二维正交各向异性板的有限元模型.简化之后的有限元模型几何外形简单，单元和自由度的数量大幅降低，减少了计算时间，提高了计算效率.通过对比三维波形钢腹板组合箱梁有限元模型的自振频率计算结果、二维等效正交各向异性板组合箱梁有限元模型的自振频率计算结果以及实测频率值，发现三者吻合良好，验证了等效模型有限元建模方法的正确性和可靠性.研究结论可为波形钢腹板组合箱梁桥提供一种简单的有限元建模方法.

Abstract: To simplify the 3D finite element modeling process for composite box girders with corrugated steel webs, the finite element model for 3D corrugated steel webs was reduced to one for 2D orthotropic plates with the equivalent stiffness and displacement method. The simplified finite element model has a trim geometric shape, a much smaller element number and less degrees of freedom, reduced calculation time, and improved computation efficiency. Comparison between the calculated results of the natural frequencies of the 3D corrugatedsteelweb composite box girder model, the calculated natural frequencies of the equivalent 2D orthotropicplate girder model, and the measured frequency values shows good agreement, which verifies the correctness and reliability of the equivalent method. The research provides a simple finite element modeling method for composite box girders with corrugated steel webs.
