• Abstract:
  Field experimental measurements and analytical studies showed that the link-slab reinforcement ; experiences almost no axial load due to thermal and gravity loading. One of the fundamental ; reasons for the low loads in the link-slab reinforcement is the fact that there is a small space ; (tolerance) between the dowel restraint bars located within the bearing at the bottom of each ; girder and the cast-in holes in the girder. Further, concrete shrinkage causes a crack to occur at ; the construction joint; the crack width is larger than the deformations caused by thermal and ; gravity loading. Thus, no link-slab moments can be generated in the deck. The authors ; concluded that the top layer of longitudinal deck reinforcement would be sufficient for link-slab ; reinforcement.
