SYNOPSIS This paper presents the results of a study of the horizontal shear resistance of the connection between full-depth precast concrete bridge deck panels and prestressed concrete girders. This connection consists of isolated shear connectors extending from the precast I-girder into a block-out pocket in the precast deck panel. The blockouts and the haunch between the panel and the beam are grouted. Thirty-six push-off tests were performed to investigate the strength and behavior of the

In addition, several alternate shear connector details were tested. It was found that of currently available horizontal shear resistance equations, the one presented in the AASHTO LRFD Bridge Design Specifications was the best predictor of the strength of the specimens. Conclusions or recommendations in this report are the opinions of the authors. PCI assumes no responsibility for the interpretation or application of the information contained herein.
