悬索桥钢箱梁桥面正交异性板局部承压试验与理论分析

Experiment and Theoretical Analysis of Local Compression of Orthotropic Plates of Steel Box-girder of Suspension Bridge

正交异性板局部承载力对钢箱梁结构非常关键,我国桥梁设计规范也没有相关规定。以广州珠江黄埔大桥悬索桥钢箱梁局部承压试验为例,介绍了钢箱梁桥面正交异性板局部承压试验的内容、方法和实际加载方案等,通过对实测结果与理论计算值进行对比研究,进而对正交异性板承载力计算理论进行分析。

The local stability of stiffened plates is a key issue in the design of orthotropic steel box girders, which has not yet been included in the specifications of bridge design. The paper takes the Huangpu Bridge of Pearl River in Guangzhou as an example and introduces the content.method and scheme of capacity experiment on the basis of research and various design specifications at home. A method of calculating the strength of orthotropic plate is analyzed by comparing data with theoretical values.
