| 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. |
