註釋Results of a previous investigation showed that the use of glass fibre reinforcement in laminated wood beams should be investigated in detail. This report describes a subsequent research project that investigated the improvement in mechanical properties of laminated wood specimens with glass fibre reinforcing. Specifically, the project evaluated the strength & stiffness enhancement of beam specimens by comparing the properties of reinforced and unreinforced beams. The test program studied specimens reinforced with glass fibre along the extreme tension wood fibre at varying amounts of fibre or fibre fractions; specimens with similar fibre fractions, but reinforced along both the extreme tension wood fibre and the extreme compression wood fibre; specimens with a different base size of laminated beam to determine sizing effects, if any; and specimens exposed to adverse environmental conditions to determine the effectiveness of the reinforcing systems to environmental exposure. In addition, a model was developed to predict the failure load of the reinforced specimens. Model predictions are compared to the experimental results.
