Diaphragm shear strength and stiffness of aluminum roof panel assemblies

摘要

A diaphragm is an assembly of planar structural elements interconnected to each other to provide in plane bracing system and transmit in-plane forces. The diaphragm geometry, supporting frame, type of the panel profiles, the way the panels are attached to each, other and to the diaphragm frame govern the overall behavior of diaphragm systems. Full scale testing is the best way to understand the overall behavior and determine the strength and stiffness of diaphragm systems.
