ASTM D7199-07(2012)

1.1 This practice covers mechanics-based requirements for calculating characteristic values for the strength and stiffness of reinforced structural glued laminated timbers (glulam) manufactured in accordance with applicable provisions of ANSI/AITC A190.1, subjected to quasi-static loadings. It addresses methods to obtain bending properties parallel to grain, about the x-x axis (F_bx and E_x) for horizontally-laminated reinforced glulam beams. Secondary properties such as bending about the y-y axis (F_by), shear parallel to grain (F _vx and F_vy), tension parallel to grain (F_t), compression parallel to grain (F_c), and compression perpendicular to grain (F_c⊥) are beyond the scope of this practice. When determination of secondary properties is deemed necessary, testing according to other applicable methods, such as Test Methods D143, D198 or analysis in accordance with Practice D3737, is required to establish these secondary properties. Reinforced glulam beams subjected to axial loads are outside the scope of this standard. This practice also provides minimum test requirements to validate the mechanics-based model.
