Abstract
Closed form expressions for the flexibility and fastener forces are developed for metal corrugated shear diaphragms. The formulas are applicable to both direct and indirect shear transfer cases. The development is based on a simple deformation mode observed in tests. Application of the method to two welded diaphragms and six screw-connected diaphragms shows that the calculated strengths and flexibilities compare favorably with the experimental data and finite element analyses.
