SP-10DESIGN CAPACITIES3.1 GeneralPanel design capacities listed in Tables 3.1 through3.4 are minimum for grade and span rating. Tables 3.1.1through 3.4.1 list allowable increases in capacity for specificpanel constructions and grades. To take advantageof these, the specifier must insure that the correct panel isused in construction.The tabulated capacities and adjustment factors arebased on data from tests of panels manufactured in accordancewith one or more of the standards listed in Section2.1 and which bear the trademark of a qualified inspectionand testing agency.Structural panels have a strength direction and a crosspanel direction. In general, the strength direction is alongthe standard 8-ft. length and the weaker direction is in the4-ft. direction. This is illustrated in Figure 3.1.Figure 3.1 Structural panel withstrength direction acrosssupports.4-ft TypicalStrengthDirection8-ft Typical3.2 Flexural Bending CapacitiesPanel design capacities listed in Table 3.1 are based onflat panel bending as measured by testing according to principlesof ASTM D3043 Method C (large panel testing).Figure 3.2 Example of structuralpanel in bending.Stiffness (EI)Panel bending stiffness is the capacity to resist deflectionand is represented as EI. The E is the modulus ofelasticity of the material and the I is the moment of inertiaof the cross section. The units of EI are lb.-in. 2 per foot ofpanel width.Strength (F bS)Allowable bending strength capacity is the designmaximum moment, represented as F b S. The F b is the allowableextreme fiber stress of the material and the S isthe section modulus of the cross section. The units of F b Sare lb.-in. per foot of panel width.3.3 Axial CapacitiesAxial Stiffness (EA)Panel axial stiffnesses listed in Table 3.2 are basedon testing according to the principles of ASTM D3501Method B. Axial stiffness is the capacity to resist axialstrain and is represented as EA. The E is the axial modulusof elasticity of the material and A is the area of thecross section. The units of EA are lb. per foot of panelwidth.APA – The Engineered Wood Association
