For measuring modulus of rupture（MOR）and modulus of elasticity（MOE）of structural plywood, the three methods were established on a single loading point with the span of 220 mm and 340 mm, and double points with 357 mm span. The test results indicated that there was an obvious linear relativity among the MOR values, while the MOE values were different from each other distinctly. The authors concluded that these methods could be comparable to each other for measuring MOR of plywood, but incomparable for measuring MOE.
