sill-beams (also called ground-sills or sole-pieces, at the bottom of a wall into which posts and studs are fitted using tenons), noggin-pieces (the horizontal timbers forming the tops and bottoms of the frames of infill panels), wall-plates (at the top of timber-framed walls that support the trusses and joists of the roof).
Composite deck boards are sold in either grooved or solid sided versions. The grooved composite board is fastened with hidden deck fasteners or clips, while the solid board is typically face-screwed. Most composite deck board manufacturers produce lengths of 12, 16, or 20 feet (3.7, 4.9, or 6.1 m), 5 + 1 ⁄ 2 by 3 ⁄ 4 inch (140 mm × 19 mm).
A slab deck is one where the deck is analyzed as a plate. If the slab has a stiffness that is different in two directions (at right angles), then the deck is known and analyzed as an orthotropic deck. A beam and slab deck is one where the beams may deflect somewhat independently, and any transverse forces are carried in the deck. A cellular ...
In light-frame construction, a trimmer is a timber or metal beam (joist) used to create an opening around a stairwell, skylight, chimney, and the like. Trimmers are installed parallel to the primary floor or ceiling joists and support headers, which run perpendicular to the primary joists.
Purlin plates are beams which support the mid-span of rafters and are supported by posts. By supporting the rafters they allow longer spans than the rafters alone could span, thus allowing a wider building. Purlin plates are very commonly found in large old barns in North America.
The T-beam has a big disadvantage compared to an I-beam (with 'Ɪ' shape) because it has no bottom flange with which to deal with tensile forces, applicable for steel section. One way to make a T-beam more efficient structurally is to use an inverted T-beam with a floor slab or bridge deck joining the tops of the beams. Done properly, the slab ...
To add rigidity to the construction of mining tunnels, the cross-beam connecting between arches is also a type of cross brace. They are often tubular and modified on the ends with clips or apertures for screw fastening. They serve as a stiffening element for the stability of a design. This brace could also be an ordinary cross-section wooden ...
The CJ-Series Joists are capable of supporting larger floor or roof loadings due to the attachment of the concrete slab to the top chord of the composite joist. Shear connection between the concrete slab and steel joist is typically made by the welding of shear studs through the steel deck to the underlying CJ-Series Composite Steel Joist. [2]
