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
Publisher: American Society of Civil Engineers
Prestress Loss of a New Vertical Prestressing Anchorage System on Concrete Box-Girder Webs
Publisher: American Society of Civil Engineers
Abstract: A new, double-tensioned prestressing steel strands anchorage system (DTPSSAS), characterized by low prestress loss caused by prestressing tendon retraction, is described. When it is used for short prestressing tendons in ...
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 ...

Rheological Behavior, Segregation, Microstructure, and Construction Quality of Cement-Emulsified Asphalt Mortar with Associative Thickener
Publisher: American Society of Civil Engineers
Abstract: Cement-emulsified asphalt mortar (CAM) is a critically important engineering material for a slab ballastless track. Segregation, which results in a density difference between the upper and lower part of the hardened CAM, ...
