Glued Laminated Wood

The author suggests that many of the limitations of solid structural timbers can be overcome with laminated products. Laminated beams can add beauty to buildings while providing many structural advantages. This report includes comparative strength values of solid timbers and laminated timbers. The stress tests include bending, tension with grain, compression with and across grain, horizontal shear, and modulus of elasticity. The outer laminations of the beam are responsible for supporting the bulk of the load. It was found that wood on the outside of the curve is in greatest tension, and wood on the inside of the curve in greatest compression.
