RISDirect Shear Strength of UHPC Large-Keyed Epoxy Joint: Theoretical Model and Experimental Verification
Publisher: ASCE
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 ...
Closure to “Prestress Loss of a New Vertical Prestressing Anchorage System on Concrete Box-Girder Webs” by Xudong Shao, Rensheng Pan, Hua Zhao, and Zixuan Shao

Shear Capacity of Ultrahigh-Performance Concrete with Monolithic Interface and Wet-Joint Interface
Publisher: ASCE
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 ...
Experimental and Numerical Investigation on the Anchorage Zone of Prestressed UHPC Box-Girder Bridge
Publisher: ASCE
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 ...
