Hence, the modulus of rigidity, G, of glulam was measured by vibration test method in order to realize the shear deflection effect. The E/G values of Japanese cedar, Taiwania, Douglas-fir, and southern pine glulam were ranged form 13.2 to 14.5, 14.6 to 16.6, 12.1 to 16.6 and 16.0 to 19.1, respectively. The pure MOE was also obtained. The Ep and MOR values of glulam were ranged from 10.6 to 13.4 GPa and 48.3 to 61.9 MPa for Japanese cedar, ranged from 12.1 to 15.0 GPa and 41.8 to 58.8 MPa for Taiwania, ranged from 10.5 to 16.4 GPa and 37.2 to 65.6 MPa for Douglas-fir, ranged from 14.5 to 20.6 GPa and 70.2 to 78.48 MPa for Southern pine, respectively.
