Abstract:
The structural behavior of Segmental Precast Post-tensioned Reinforced Concrete (SPPRC) beams largely depends on thebehavior of the joints that connect between the segments. In this research, series of static tests were carried out to invest igatethe behavior of full-scale SPPRC beams with different types of epoxy-glued joint configurations; multi-key joint, singlekey, and plain key joint. The reference specimen was monolithically casted beam and the other specimens were segmentalbeams with five segments for each one. The general theme from the experimental results reflects an approximate similarityin the behavior of the four beams with slight differences. Due to the high tensile strength of the used epoxy in comparisonto concrete, cracks at joints occurred in the concrete cover which was attached to the epoxy mortar.
