Average bending strength of water-soaked glulam beams was slightly, but not significantly, higher than predicted based on dry beam tests and the adjustment factor presently recommended. The recommended wet-use factor of 0.80 is within the 95 percent confidence interval for the mean effect, and no change appears warranted. The average bending stiffness of the water-soaked glulam beams was significantly higher than predicted based on dry beam tests and the recommended adjustment factor. The best estimate of the wet-use MOE factor is 0.89 with a 95 percent confidence interval extending from 0.85 to 0.95-the present recommended factor is 0.833. However, due to the possibility of increased deflection under cyclic wet and dry conditions, caution is recommended before changing to a higher wet-use factor for MOE. (Author).
