A critical review on shear performance of joints in precast Ultra-High-Performance Concrete (UHPC) segmental bridges

Precast Ultra-High-Performance Concrete (UHPC) segmental bridges (PUSBs) are among the most promising structural systems owing to their potential for application in advanced philosophies, such as green and intelligent construction technology, industrialization, prefabrication, and automation. The joints, where precast segments are connected, play a significant role in the construction and structural performance of PUSBs. This study reviews the state-of-the-art knowledge on the shear behavior of UHPC joints, which includes the following aspects: (1) the introduction of joints in PUSBs, including their role, types, experimental methods, and typical shear responses; (2) the development of the experimental database of the push-off tests conducted on UHPC joints; (3) a discussion of the influence of critical factors (e.g., UHPC strength, joint type, confining stress, fiber characteristics, and shear key design) on the shear behavior of UHPC joints; (4) a summary and evaluation of the current analytical models and formulae for predicting the shear resistance of UHPC joints; and (5) the identification of current challenges and recommendations of future research directions for UHPC joints. This review is expected to comprehensively understand the shear performance of UHPC joints and facilitate the research and application of UHPC structures.
