A double floor is a floor framed with joists supported by larger timbers.. In traditional timber framing there may be a single set of joists which carry both a floor and ceiling called a single floor (single joist floor, single framed floor) or two sets of joists, one carrying the floor and another carrying the ceiling called a double floor (double framed floor).
Rim joists are not to be confused with end joists, which are the first and last joists at the ends of a row of joists that make up a floor or deck frame. A rim joist's relationship to the joists is similar to what the top or bottom wall plate is to the studs. It is also confusingly called a header (header also refers to other framing components ...
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.

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
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]
Glulam beams were used to support the second floor and the roof. This allowed the appearance of wooden columns, while providing the necessary strength. [2] The method for calculating the size of a flitch beam to be used in construction is straightforward, using the transformed-section method.
An I-beam used to support the first floor of a house An I-beam is any of various structural members with an Ɪ- (serif capital letter 'I') or H-shaped cross-section . Technical terms for similar items include H-beam , I-profile , universal column ( UC ), w-beam (for "wide flange"), universal beam ( UB ), rolled steel joist ( RSJ ), or double-T ...
The waffle slab floor system has several advantages: Better for buildings that require less vibrations – this is managed by the two way joist reinforcements that form the grid. Bigger spans can be achieved with less material, being more economical and environmentally friendly; Some people find the waffle pattern aesthetically pleasing [4]
