NPS® Cls Beam

The self-bearing NPS® Cls Beam with a mixed steel-concrete structure is fire-resistant in conformity to Eurocode 2-2. It is ideal for fire-resistant structures with large overloads and/or spans; it is particularly suited to coupling with hollow core slab or slab ceilings.

The metal structure, made of structural steel (UNI EN 10025-2), with EN 1090-1 CE marking, is made of one or more trusses welded using metal active gas welding (Process UNI EN ISO 4063-135) according to current NTC 2008.

The lower chords are inserted in a class C28/35 concrete footing (UNI EN 206-1:2006), precast and equipped with reinforcement and surface reinforcement sized to support the load of the heavy ceilings on NPS® Cls Beam.

Technical data

Metal structure Made of structural steel in conformity with UNI Standard UNI EN ISO 10025-2
Footing C28/35 or higher class concrete (UNI EN 206-1:2006) designed and equipped with reinforcement and surface reinforcement. Acts as a ceiling support and formwork for the casting formwork
Casting framework C25/30 when not otherwise noted by the designer
Self-supporting Yes. NPS® Cls Beam bears itself and the ceiling that rests on it, already from the moment it is placed on the column (1st phase), already before the formwork cast (2nd phase)
Welding Using metal active gas welding (Process UNI EN ISO 4063-135) according to NTC 2008 in force
Mechanical resistance to fire ( R ) Up to 240 minutes
Standards referenced In the 1st phase § 4.2 NTC 2008 and Eurocode 3 In the 2nd phase § 4.3 NTC 2008 and Eurocode 4 For anti-seismic § 7.6 NTC 2008 and Eurocode 8
Design Elaborated with the System calculation procedure conforming to the current Standard, and signed by a qualified technician.

Cls beams are connectable with all types of columns, and adapt to different support shapes in use. It is ideal for realising decks with jumps in height, thanks to the footing that can be shaped with different heights on two sides.
