Representative shear strength test methods to evaluate the shear strength of laminated veneer lumber(LVL) circulated in domestic lumber market were compared each other. ASTM shear block test and JAS and ISO short-span center point bending test were conducted to the LVL with the thickness of 25 ㎜ and 30 ㎜. In the case of ASTM shear block test and ISO/JAS short span bending test, the ultimate load were not significantly different. The ratio of short span bending test to shear blocktest were 1.10 in 25 ㎜ LVL and 0.74 in 30 ㎜ LVL. The linear regression analyses between shear block test and short span bending test were conducted and weak relationship were found. Furthermore, the linear regression analyses between shear strength from each methods and bending strength or MOE were observed to be no significant relationship. The short-span center point bending test showed shear failure rather than bending failure and the glueline failure between lamination was not found. The short span center point bending test was considered to be effective test method to evaluate the shear strength of laminated veneer lumber. Further works on the optimal test methods are required to evaluate the precise shear strength of structural composite lumber in actual size.
