Structural Members Unit 6
Structural Components • Floor joists range from 2” X 6” to 2” X 14” and spaced at 12”, 16”, or 24” • Mudsill rests on the masonry foundation • Provides a base for all framing • Attached to foundation with anchor bolts • Either 3/4” or 5/8” in diameter
Structural Components • Joists will tend to roll as loads are applied • Blocking is used at the center of the joist span to help transfer lateral loads • Sheathing is placed over the joists to form the subfloor • Face grain should be perpendicular to the floor joists
Beams • Girder (beam) is used to support the floor • A flitch beam consists of steel plates bolted between wood members • Glu-lam beams are laminated with sawn lumber and more structurally stable • Engineered wood girders consists of laminated veneer strips glued together
