Abstract: With the development trend of accelerated bridge construction, the precast ultra-high-performance concrete (UHPC) segmental bridge might be increasingly used due to the advantages of lightweight superstructure and advanced ...

Abstract: The bonding interface serves as a vulnerable point in steel structures strengthened with carbon fiber–reinforced polymer (CFRP), significantly influenced by the mechanical properties of adhesives and temperature. To ...

Abstract: Ultrahigh-performance concrete (UHPC) holds tremendous potential in addressing the issues of short service life and lack of reasonable impact resistance characterization in the anchorage zone of bridge expansion joints, ...

Abstract: The structural performance of reinforced concrete bridges gradually deteriorates due to material aging and concrete cracking. Reported here are the experimental investigations and the nonlinear finite-element analysis of ...

Abstract: A total of 65 Z-shaped ultrahigh-performance concrete (UHPC) specimens with monolithic interfaces, flat-wet-joint interfaces (roughened with a high-pressure water jet), and keyed-wet-joint interfaces were tested under the ...

Abstract: The structural behavior of the anchorage zone is a key issue in prestressed ultra-high performance concrete (UHPC) box-girder bridges. This study investigates the mechanical behavior of a diaphragm–blister integrated ...
