Abstract In this study, precast concrete (PC) wide girders were developed to secure economic efficiency by reducing the amount of slab volume resulting from enabling to shorten the span length of slab. A total of three PC wide girder-column joint specimens were fabricated with different details of reinforcing bars penetrating beams and columns in the joint region. Reversed cyclic loading tests were then conducted to evaluate structural performance, from which the lateral behavior of all the specimens were compared in detail. In addition, seismic performance of the proposed PC wide girder-column joints was quantitatively evaluated based on the acceptance criteria of the ACI 374 report.
