The American Iron and Steel Institute (AISI) has published AISI D310-14, “Design Examples for the Design of Profiled Steel Diaphragm Panels Based on AISI S310-13.” The design guide is the supporting document for AISI S310, North American Standard for the Design of Profiled Steel Diaphragm Panels (which was published in September 2014). Both documents are available in PDF format as free downloads at

Approved by the AISI Committee on Specifications Diaphragm Task Group, AISI D310-14 provides five design examples that illustrate the application of design provisions in AISI S310. The Standard provides design provisions for diaphragms consisting of profiled steel decks or panels, including acoustic panels, cellular deck, and composite deck filled with concrete. The illustrative examples determine the strengths and stiffness of diaphragms formed with wide rib decks, profiled panels, and panels with insulation, and with various support materials and loading conditions.
