摘要:

从畸变基本理论出发,推导得到不同横隔板间距条件下钢箱梁横隔板最小刚度的计算理论及公式。在此基础上根据能量守恒原理,明确了横隔板最小刚度公式的适用范围。采用有限元分析方法,研究了常规钢箱梁截面横隔板间距不同对畸变效应的影响,在此基础上分析并解决了钢桥规范公式在计算较小间距横隔板却需要超厚横隔板的问题,为常规钢箱梁合理设置横隔板提供明确的理论指导。以在建“世界第一跨径钢混组合梁桥”为背景桥梁,设计大比例缩尺试验研究扭转工况下横隔板刚度变化对钢箱梁变形的影响。采用了3D扫描技术和三维有限元方法对试验结果进行分析,研究表明横隔板刚度在提供基本约束的情况下,横隔板刚度变化对箱梁畸变效应的影响十分有限。

Abstract:

This paper, based on fundamental distortion theory, derives theoretical formulas for calculating the minimum diaphragm stiffness of steel box girders under different diaphragm spacing conditions. On this basis, using the principle of energy conservation, the applicable range of the minimum diaphragm stiffness formula is clarified. Finite element analysis is used to study the impact of varying diaphragm spacing on the distortion behavior of conventional steel box girder sections. This analysis addresses and resolves the issue present in design codes, where excessively thick diaphragms are required for small spacings, providing clear theoretical guidance for the rational placement of diaphragms in conventional steel box girders. Using the "world's longest-span steel-concrete composite girder bridge under construction" as a case study, a large-scale reduced model test was designed to investigate the impact of diaphragm stiffness variations on the deformation of steel box girders under torsional conditions. 3D scanning technology and finite element methods were employed to analyze the test results, and the research shows that once the diaphragm stiffness provides basic constraints, further changes in stiffness have a very limited effect on the distortion behavior of the box girder.

Key words: bridge and tunnel engineering, steel box girder, distortion angle, elastic foundation beams, diaphragm thickness, diaphragm spacing
