SynC · Topic
These are the standards in the SynC Standards library that cover Joists. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Structural cold-formed steel framing designed under AISI S100 and AISI S240 and, where the framing participates in a seismic force-resisting system, AISI S400. Covers load-bearing stud walls, exterior non-load-bearing wind-bearing wall framing in both infill and bypass arrangements, cold-formed steel floor joists, roof rafters, and trusses, cold-formed steel shear walls and braced walls, and the parapet, canopy, and soffit framing that carries calculated load. Addresses the division of design responsibility between the Engineer of Record and the specialty engineer, sheet steel and metallic coating selection, member designation and identification, out-of-plane deflection criteria, movement accommodation at the head of wall, bridging and bracing, screwed, welded, powder-actuated, clinched, and bolted connections, opening and built-up member framing, web penetrations and field modification, erection tolerances, listed fire-resistance-rated assemblies, and field inspection.
Open-web steel joists and joist girders furnished by Steel Joist Institute member manufacturers under ANSI/SJI 100 and erected under ANSI/SJI 200. Covers K-series and KCS joists, LH-series and DLH-series long-span joists, G-series joist girders, and CJ-series composite joists. Addresses the delegated-design relationship between the Engineer of Record and the joist manufacturer, joist and erector qualification, chord and web steel selection, deflection and floor-vibration criteria, camber policy, bearing seat depth and end anchorage, bridging type and attachment, headers at framed openings, chord extensions, erection stability and erection bridging under OSHA 29 CFR 1926 Subpart R, erection tolerances, shop coating selection, field touch-up, and field inspection of joist work.
