Abstract
A refined yet simple method is presented for the analysis of cold-formed metal shear diaphragms. Expressions for the deflections and fastener forces are developed based on an assumed mode of deformation in conjunction with a refined set of internal force distributions. The formulas are applicable to both 'direct' and 'indirect' shear-transfer cases. The generality and the accuracy of the derived expressions are illustrated in an application of the method to the analysis of eight diaphragms having a wide range of constructional details. The results of calculations for the diaphragm flexibility and strength are in good agreement with test results and with finite-element analyses.
