SW-6INTRODUCTIONFor the purposes of this Supplement, the following assumptionsare made:• These assemblies act as deep beams.• In-plane shear resistance is provided by the wood structuralpanels.• Axial tension and compression resistance is providedby the chord members (flange action).• Nailed assemblies, as shown in Tables 3.1A, 3.1B, 4.1Aand 4.1B, exhibit ductile, energy absorbing behavior.While shear resistance of these assemblies can becomputed by principles of engineering mechanics (seeTissell and Elliot, 1997), it is recommended that designersuse Tables 3.1A, 3.1B, 4.1A and 4.1B for typical designpurposes. In addition to eliminating labor intensive calculations,these tables limit configurations to those thathave proven to exhibit the aforementioned ductile behaviorby demonstration via structural testing and years ofsuccessful in-use performance.2.4 Inspection and Testing AgenciesAdditional information is available from organizationsproviding trademarking and quality assurance services:APA - The Engineered Wood Association7011 South 19th StreetP.O.
