Standard K-Series Joists have a 2 + 1 ⁄ 2 inches (64 mm) end bearing depth so that, regardless of the overall joist depths, the tops of the joists lie in the same plane. Seat depths deeper than 2 + 1 ⁄ 2 inches (64 mm) can also be specified.
Wall framing in house construction includes the vertical and horizontal members of exterior walls and interior partitions, both of bearing walls and non-bearing walls. . These stick members, referred to as studs, wall plates and lintels (sometimes called headers), serve as a nailing base for all covering material and support the upper floor platforms, which provide the lateral strength along a
Trimmers are installed parallel to the primary floor or ceiling joists and support headers, which run perpendicular to the primary joists. [1] [2] It can also refer to a jack stud that supports a header above a window or door opening. Traditionally, a stud which was less than full length was sometimes referred to as a cripple.

Posts in walls are used at point loads such as long spans near a wide window or sliding door, etc. sleeper or nailer - a stud laid flat to other framing members to provide a point of attachment. sill - a stud sized member forming the base of a window assembly or the base of wall.
Often found at the centerline of the house to support one end of a joist, and to bear the weight of the structure above. [83] Spandrel 1. In a building facade, the space between the top of the window in one story and the sill of the window in the story above. 2. The space between two arches or between an arch and a rectangular enclosure. Spere
The term binding joist is sometimes used to describe beams at floor level running perpendicular to the ridge of a gable roof and joined to the intermediate posts. Joists which land on a binding joist are called bridging joists. [4] [5] A large beam in the ceiling of a room carrying joists is a summer beam. A ceiling joist may be installed flush ...
[5] [3] As a rule of thumb, the depth should be 1 ⁄ 24 of the span. [5] The width of the ribs is typically 130 mm (5 in) to 150 mm (6 in), and ribs usually have steel rod reinforcements. [5] The distance between ribs is typically 915 mm (3 ft). [3] The height of the ribs and beams should be 1 ⁄ 25 of the span between columns. [3]
Joist bridging, or blocking, is used between floor or ceiling joists, but this is to prevent the joists from (twisting or rotating under load) rather than to prevent buckling in compression. Herringbone strutting may replace blocking with smaller, timber battens fixed diagonally, in pairs, between joists.
