中文摘要	为了改善组合箱梁桥杆系模型研究尚不成熟的现状,提出了组合箱梁桥的杆系模型。首先以分格室结构的剪力-柔性梁格理论为基础,确立了构件层次和截面层次的建模策略;进而以简支组合箱梁桥和连续组合箱梁桥、直线组合箱梁桥和曲线组合箱梁桥为研究对象,分别建立精细模型和杆系模型,进行模态分析、恒载和活载作用下的静力分析。研究结果表明:精细模型和杆系模型的计算结果吻合良好,杆系模型具有良好的准确度与适用性;研究成果为杆系模型在实际组合箱梁桥设计分析中的应用奠定了基础。; In order to further research beam-truss modeling of steel-concrete composite box-girder bridges,the beam-truss model of composite box-girder bridges was proposed and implemented.Firstly,modeling strategy for member and section level was established based on shear-flexible grillage theory applied to the cellular deck.Furthermore,modal analysis and static analysis under dead and live load were conducted for composite simply supported and composite continuous boxgirder bridges,the alignments of which included straight and curved.The results show that high accuracy and good applicability of beam-truss model of composite box-girder bridges can be verified due to good correlation of numerical results between elaborate and beam-truss FE model.The research in this paper has laid the foundation for the further application of beam-truss model in the design analysis of actual composite box-girder bridges.
