SynC · Topic
These are the standards in the SynC Standards library that cover Seismic Bracing. 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.
Factory-fabricated sheet-steel lockers and their doors, latching, locking, trim, interior equipment, and anchorage, in knocked-down or welded construction, for school corridors, athletic and team rooms, employee and industrial change rooms, public recreation, and day-use storage. Covers substrate selection and corrosion protection, component sheet thickness, tier and opening configuration, door ventilation, latching and locking including electronic locks, powder-coat finish performance, tops, bases and closure trim, accessible lockers under the ADA Standards and ICC A117.1, and floor, wall, and seismic anchorage.
The bolted and welded connections that join hot-rolled structural steel framing members into a load-carrying structure: simple shear connections, fully restrained and partially restrained moment connections, vertical and horizontal bracing connections and their gusset plates, column splices, and the steel side of column base plate connections. Covers the assignment of connection design responsibility under AISC 303, the joint condition (snug-tight, pretensioned, or slip-critical) for each connection class, high-strength bolt assemblies under ASTM F3125 and their finish, the RCSC pretensioning methods and pre-installation verification, faying surface slip class and treatment, bolt hole types, the backing, weld tab, and access hole configurations at connection groove welds, load sharing between bolts and welds, the connection provisions AISC 341 imposes on the seismic force-resisting system, bolting inspection, and the handling of fastener assemblies.
Direct-hung metal suspension grid systems and acoustical panels or tiles — both exposed-tee lay-in and concealed-spline — for commercial, institutional, healthcare, educational, and hospitality interiors. Covers the suspension grid (type, profile, duty classification, and finish), acoustical panels (material, size, edge detail, and surface texture), acoustical performance (NRC and CAC), light reflectance, surface-burning fire performance, fire-resistance-rated ceiling membrane assemblies, seismic restraint and perimeter treatment, hold-down clips, trim and moldings, hanger wire and bracing, and integration with light fixtures, air devices, and sprinkler heads.
