Description: Connections between steel side plates and white oak glued-laminated beams subjected to tension perpendicular-to-grain stresses were tested to failure. The beams were then repaired with five different configurations using two sizes of lag screws, with and without steel reinforcing plates. The repaired beams were re-tested to failure. Results indicate that in all cases the repaired beams had greater ultimate loads than did the original beams. Results also indicate that lag screws without the reinforcing plate are sufficient for repair.
