1 Table values assume a simply supported panel with 1.5 in. of continuous bearing on facing at supports (Cv = 1.0) with solid wood plates
at bearing locations. Values do not include the dead weight of the panel. For wall panel capacities (4-5/8 in., 6-1/2 in. and 8-1/4 in.
thickness panels only) utilizing a zero bearing configuration (Figure 2), the allowable load shall be determined using Cv = 0.4.
2 Deflection limit shall be selected by building designer based on the serviceability requirements of the structure and the requirements of
adopted building code. Values are based on loads of short duration only and do not consider the effects of creep.
3 Tabulated values are based on the strong-axis of the facing material oriented parallel to the direction of panel bending. WAB indicates
weak-axis bending of the facing material; the strong-axis of the facing material is oriented perpendicular to the direction of panel bending.
4 Permanent loads, such as dead load, shall not exceed 0.50 times the tabulated load.

1 Permanent loads, such as dead load, shall not exceed 0.50 times the tabulated load.
2 All values are for normal duration and may not be increased for other durations.
3 Axial loads shall be applied concentrically to the top of the panel through repetitive members spaced
not more than 24 in. on center. Such members shall be fastened to a rim board or similar member to
distribute along the top of the SIP.
4 The ends of both facings must bear on the supporting foundation or structure to achieve the tabulated
axial loads.
5 Tabulated values are based on the strong-axis of the facing material oriented parallel to the direction
of panel bending. WAB indicates weak-axis bending of the facing material; the strong-axis of the facing
material is oriented perpendicular to the direction of panel bending.
