Abstract

In prefabricated concrete structures, the joints between the prefabricated components are crucial for the overall performance of the structure. However grout suffers from high brittleness and poor toughness. To enhance the mechanical connection performance of prefabricated structural joints, unidirectional pull-out tests were conducted on grout sleeve joint specimens with varying anchoring lengths, incorporating polyacrylonitrile (PAN) fibers into the grout material. The results show that, due to the ‘bridging effect’ of PAN fibers, the total tensile displacement of the joint specimens increases to varying degrees, and the extent of brittle failure is reduced. Additionally, as the anchoring length decreases, the addition of PAN fibers increases the strain value of the cylinder wall.
