横向整固T梁桥复合桁架技术的分析研究

Analysis and Research on Composite Truss Technology of Transverse T-beam Bridge

提出长通底梁K型、分离底梁K型、长通底梁三角型以及分离底梁三角型复合桁架4种横向整固桁架结构,借助三维有限元ABAQUS模拟计算系统,围绕中载及偏载两种载荷工况,对横向整固T梁桥4种复合桁架技术方案作择优对比分析,对工程应用有技术参考价值。

Four types of horizontally consolidated truss structures are proposed:K-shaped long-pass bottom beam,K-shaped separated bottom beam,triangle-shaped long-pass bottom beam,and triangular composite truss with the separated bottom beam.With the aid of the three-dimensional finite element ABAQUS simulation calculation system,focusing on the two load conditions of medium load and eccentric load,the four kinds of composite truss technical schemes for transverse consolidation of T-beam bridges are compared and analyzed.The results have technical reference value for engineering applications.
