摘要
以某单线铁路48 m简支槽型梁为工程背景,对其结构选型和设计进行了简要介绍。采用有限元分析软件进行了杆系及实体分析,对结构的剪力滞后效应和弯扭稳定性进行了重点介绍,计算分析结果表明设计安全、可靠,可为同类型的桥梁设计提供一定参考。
Based on a simply supported U-shaped beam with a span of 48m in a single-track railway, this paper introduces its structural selection and design briefly. It analyzes the bar-system and entity structure with finite-element method, and fo- cuses the discussion on shear-lag effect and flexural torsional stability of the structure. The results show that the design is safe and reliable, and the study could be referred to by the same type of bridges.
