Abstract
Use of pultruded composites to rejuvenate low aspect ratio timber beams is
described. Loss of shear resistance is restored by inserting fiberglass pultruded
rods from the bottom to the top of the beam, through areas of damage. An
adhesive is incorporated during the process of insertion, which bonds the
reinforcing rods in-place and fills adjacent cracks. Scale beam testing, with a
variety of reinforcement cases, has been performed and the overall results are
extremely positive, with test beams showing strong recovery of flexural
properties and improvement in the strain to failure.
