Analysis and Design Methods on Stress of Hogging Moment Zone of Steel-concrete Composite Girder

摘要:

通过深入调研分析上海市区管交通标志和标线的管理现状，梳理了区管交通标志和标线在实际管理中主要存在，人员、技术、资金、机制和管理缺口等五个方面的问题，并针对上述问题提出了，包括建立设施量统计数据库，出台统一的养护技术规范及定额标准，定期开展人员培训等一系列对策和建议，对于提高上海市交通标志和标线运行管理水平、提升城市管理品质具有重要指导意义。

Abstract:

By sorting out and analyzing the factors affecting the stress performance of the hogging moment zone of composite girder, the technical measures of tensile stress and the design method of hogging moment are improved. And combined with an engineering case, the design method of hogging moment zone of steel-concrete composite girder based on the principle of State 2 is verified. And the measures and suggestions are put forward in the aspects of design and construction.
