The Major Units Laboratory at West Virginia University has been involved in full-scale diaphragm studies for the past fifteen years. The work has covered tests on a wide range of deck panel types, metal building wall systems, panels with insulating concrete fill, and plywood assemblies, all used as diaphragms, and under static, cyclic, and dynamic loading. Connection performance, critical to diaphragm behavior, has been evaluated through an extensive test program covering arc-spot (puddle) welds, different types of screws, and power driven pins. These have established fastener strength limits and have been especially important for defining fastener flexibility factors.
