Abstract
Precast deck joints have problems due to the occurrence of additional processes at construction sites, the complexity of construction, and the lack of design and construction standards for precast deck joints. To solve these, this study proposes a new precast deck joint that uses an Ultra-High-Performance Fiber-reinforced Cement Composite (UHPFRCC) filling material containing steel fibers and a straight rebar joint. In addition, the structural performance of the proposed joint, based on various parameters, was compared to that of existing precast deck joints, and the proposed joint showed equivalent strength and ductility. Therefore, the proposed joint can solve construction site problems by replacing the existing ones. The influence of various variables is expected to provide basic data on the design and construction guidelines for the precast deck joints.
