Framing

Standards

• Aluminum Entrances and Storefronts

  Non-load-bearing extruded aluminum framing systems glazed with monolithic or insulating glass, and the aluminum stile-and-rail swing entrance doors integrated with them, at building perimeters and interior partitions. Covers framing depth, sightline, joinery, glazing pocket position, and thermal barrier construction; glass lite construction, insulating glass unit make-up, edge seal, and low-emissivity coatings; dry, wet, and structural silicone glazing methods; air infiltration, water penetration, structural wind load, thermal transmittance, solar heat gain, condensation, acoustic, windborne debris, and inter-story drift performance; entrance door leaf proportions, construction, hardware, thresholds, and weatherseals; anodic and organic finishes; perimeter anchorage, sill water management, and air and water control layer continuity; laboratory and field testing; installation, cleaning, protection, and warranty.

• Cold-Formed Metal Framing

  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.

• Gypsum Board Assemblies

  Interior gypsum board partitions, furred walls, and ceilings, and the gypsum sheathing on framed exterior walls, in commercial, institutional, multifamily, and residential buildings. Covers the gypsum panel products by exposure and duty: regular, Type X, and Type C board, sag-resistant ceiling board, mold- and moisture-resistant board, glass-mat faced board, abuse- and impact-resistant board, the wet-area backer boards that carry tile on framed walls, gypsum base for veneer plaster, shaftliner in area separation walls, and glass-mat and paper-faced gypsum sheathing. Covers the nonstructural steel studs, runners, furring, and resilient channels furnished to ASTM C645 and installed to ASTM C754, the suspended and direct-attached ceiling framing that carries gypsum board, deflection heads and partition bracing, in-wall blocking and backing for the trades that hang work on these walls, execution of fire-resistance-rated and sound-rated assemblies to their design numbers, perimeter acoustic sealant and electrical box treatment, fastening, multi-layer application, trim accessories, control joints, joint treatment, levels of finish, and textured finishes.

• Miscellaneous Metals

  Utility steel items shop-fabricated for a building or plant that are not part of the primary frame on the structural drawings and carry no architectural finish requirement: fixed vertical ladders with their ladder safety systems or personal fall arrest anchorage, ship's ladders and alternating tread devices, loose steel lintels and masonry shelf angles shown outside the structural drawings, slab and curb edge angles and nosings, loose embedded steel furnished for casting into concrete by others (embed plates, weld plates, seat angles, and anchor channels serving the items of this standard and architectural metal fabrications), the angle frames of utility trench and pit covers, loose equipment supports, stands, and rooftop dunnage not furnished with the equipment, and unrated steel pipe guard posts and column and door-jamb guards that protect building elements and equipment from impact. Covers the material grade for each product form, fasteners and anchors, the shop corrosion protection policy for interior and for exterior and masonry-embedded items, the OSHA and ANSI/ASSP A14.3 fall protection decision for fixed ladders, ship's ladder geometry, lintel bearing and shelf angle segmentation, embed anchorage, trench frame material and section, dunnage clearance and design responsibility, guard post size, fill, cap, and anchorage, exposed weld treatment, installation, delivery, and warranty, in commercial, institutional, industrial, water and wastewater, and multi-family buildings.

• Steel Deck

  Cold-formed steel floor and roof deck furnished and installed under the Steel Deck Institute standards: composite floor deck acting with the concrete slab above it, non-composite form deck serving as a permanent form, roof deck carrying the roofing assembly, and acoustical roof deck. Covers the division of design responsibility for the deck and its diaphragm, manufacturer and installer qualification, sheet steel and metallic coating selection, the basis for profile, depth, gauge, and section properties, diaphragm design basis, attachment to supports by arc spot welds, arc seam welds, powder-actuated fasteners, and screws, side-lap fastening, the deck's role in a composite slab including shoring, concrete placement loads, and the sequence for shear studs welded through the deck, roof deck uplift attachment and FM Approval, openings and their reinforcement, pour stops, closures, and sump pans, placement and OSHA decking requirements, field cutting and coating repair, field inspection under the SDI quality standard, delivery and storage, and the warranty for the deck work.

• Steel Joists

  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.

• Structural Steel Framing

  The hot-rolled structural steel frame of a building or structure designed by the Engineer of Record under ANSI/AISC 360: wide-flange beams, girders, and columns, hollow structural sections and pipe used as columns, braces, and beams, channels, angles, tees, plates, and bars, built-up members, crane runway beams, and the headed shear stud connectors, stiffeners, column base plates, and stabilizer plates furnished with them. Covers the material grade for each shape family, the material provisions the seismic force-resisting system imposes on members, fabricator and erector qualification, shop and erection drawings, cutting, hole forming, straightening, cambering, and member marking, architecturally exposed structural steel categories, the shop coating system and its boundary with applied fireproofing and field finishes, erection planning, temporary bracing, column base setting, erection tolerances and the post-erection survey, field touch-up, delivery and storage, and the warranty for the structural steel.
