Experimental study on the flexural behavior of a novel prestressed tapered composite box girder with concrete-encased corrugated steel webs and steel bottom plate under negative bending

Key Points

• Flexural behavior demonstrates increased load capacity under negative bending and stability.
• Key evidence shows improved performance with a load capacity enhancement of 30% in tests.
• Experimental analysis of composite box girders with concrete-encased corrugated steel webs reveals significant insights.
• Findings highlight potential use in bridge constructions, emphasizing durability and efficiency.
