| Abstract: | The goals of this study were to develop and validate accurate stocastic models of tensile strength and modulus of elasticity (MOE) for finger joints made from E-rated laminating lumber. Accurate finger joint models are needed since glued-laminated (glulam) beam failure frequently initiates at end joints. The finger joint tensile strength and MOE models that were developed in this study will be valuable to reliability-based models that predict statistical distibutions of glulam beam strength. Finger joints tensile strength and MOE were modeled for five E-rated and two visual grades of Hem-Fir. The two visual grades, L2 and L3, were included in this study because these grades were comprised of materials that did not qualify for the E-rated grades. A recursive approach was used to simulate finger joint properties as functions of localized constituent lumber properties. Statistical distributions of finger joint tensile strength and MOE were preserved, as well as the correlation between the two. |
