Experimental and numerical study of steel-to-concrete joint section in hybrid cable-stayed bridges

Yi-Wei Gu et al.

Summary: The steel-to-concrete combination segment connecting the steel box girder and the concrete girder in a hybrid cable-stayed bridge plays a critical role in force transmission. Through experiments and finite element modeling, the force transfer mechanism, load bearing ratio, and influence of steel stiffener length in the joint section were analyzed and studied. The findings are considered significant for the design and construction of such segments in hybrid cable-stayed bridges.

Fatigue Performance of an Innovative Steel-Concrete Joint in Long-Span Railway Hybrid Box Girder Cable-Stayed Bridges

Qianhui Pu et al.

Summary: The study found that the innovative steel-concrete joint (SCJ) has favorable force transfer and deformation performance during train operation. Additionally, it was discovered that the thickness of the end bearing plate and diameter of the shear studs significantly influence the fatigue performance.

Additional Shear Stresses in Webs of Segmental Concrete Bridges due to Anchorage of Cantilever Tendons

Zhi-Qi He et al.

Summary: The study focuses on analyzing and discussing the anchorage-induced shear stresses in the webs of segmental concrete box-girder bridges, providing important factors to consider in design. The research findings suggest that ignoring the effects on the webs during cantilevering may result in a significant increase in shear stresses.
