Purpose and Scope

The purpose of this Engineering Practice is to define a test method for determination of the in-plane strength and stiffness of a metal-clad wood-frame diaphragm assembly. The design values determined by this method shall be used in accordance with ANSI/ASAE EP484 or other acceptable standards to design buildings or structural systems to resist in-plane shear forces.

This method shall be used for diaphragm assemblies constructed with roll-formed metal sheeting (e.g., steel, aluminum) attached to any type of wood framing system. If rigid or blanket insulation is to be installed between the metal sheeting and wood framing in the building being designed, identical insulation shall be installed in a similar fashion in the test assembly.
