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]
Cellular beam is a further development of the traditional castellated beam. [1] The advantage of the steel beam castellation process is that it increases strength without adding weight, making both versions an inexpensive solution to achieve maximum structural load capacity in building construction. [2] The difference between cellular beam and ...
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 ...
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. The steel plate is treated as an equally stiff piece ...
A steel Ɪ-beam, in this case used to support timber joists in a house Ɪ-beam (serif capital 'Ɪ'-shaped cross-section – in Britain these include Universal Beams (UB) and Universal Columns (UC); in Europe it includes the IPE, HE, HL, HD and other sections; in the US it includes Wide Flange (WF or W-Shape) and H sections)
A common method used is to install I-beams or rolled steel joists (RSJs). These can either be installed in single lengths or in smaller sections which are bolted together. New timber joists are then installed between the RSJs onto which the new floor can be laid. A structural engineer will calculate the size of the RSJs and joists.
