APA has published a paper entitled,"Calculation by Principles of Mechanics," which can be used to calculate theoretical shearwall values for statically loaded plywood shearwalls. At first glance, the procedure seems somewhat involved. However, the only potentially difficult step in the calculation would be the determination of the appropriate allowable load values for the screws or pneumatic pins. The Structural Engineers Association of Hawaii(which has interest in both wind and earthquake resistance) performed ssuch calculations, and found shearwall values to be slightly less than , bu comparable to, plywood and wood stud shearwall values. ( The metal stud used were of 20 to 16 gauge material.) These values are included in a more comprehensive report entitled,"Structural Guidelines for Design and Detailing of Cold-Formed Steel Framing," that is being editorially reviewed by the current SEAOH Board of Directors, and scheduled for publication soon(this year). Note: Careful design of the boundary elements is critical. Buckling and twisting of the boundary studs has resulted in premature failures for some of the tests run at the University of Santa Clara and by APA. All inquiries regarding the upcoming SEAOH guidelines booklet should be sent to : Structural Engineers Association of Hawaii P.O.
