The objective of the research was to determine if red maple glued-laminated (glulam) timber beams with design flexural strength of 16.5 MPa (2400 psi) and design stiffness of 12.4 GPa (1.8 × 106 psi) could be designed and fabricated. The strength and stiffness of red maple glulam timber beams were predicted using ASTM D3737 procedures and then compared to data from 45 test beams, 15 each of 3 sizes. The results show that ASTM D3737 procedures conservatively predict the strength and satisfactorily predict the stiffness of red maple glulam timber beams and that red maple beams with flexural strength of 16.5 MPa (2400 psi) and stiffness (MOE) of 12.4 GPa (1.8 × 106 psi) are technically feasible. Also, the volume effect for the strength of the red maple glulam timber test beams was similar to the published volume effect for softwood glulam beams.
