MMC Case Study - Steel Framing Systems in construction
The construction of a part four, part five-storey building incorporating roof terrace and balconies, comprising a commercial unit at ground floor and 9 No. self-contained flats over.
For speed of construction and cost effectiveness, we provided a design solution for the use of Steel Framing Systems (SFS). This is a lightweight, galvanised cold-formed system that consists of C-shaped and U-shaped studs and tracks that can be constructed on site or prefabricated and delivered on site.
To satisfy disproportionate collapse requirements without the need of additional hot-rolled steel frames, and for maximum open space at the commercial unit, a Reinforced Concrete (RC) “transfer” slab has been provided at first floor with RC columns on RC pad foundations. The SFS system has been provided to the rest of the floors.
- Design of the RC transfer slab, columns, shear walls and foundations
- Reinforcement layouts and bar schedules for the RC elements
- Wind analysis to obtain wind loads based on the building’s height and location
- Material cutting lists for all the SFS elements
- Design of hot-rolled steelwork where, SFS elements deemed impractical (e.g. long and/or heavily loaded trimmers, lintels etc.)
- Design of the SFS wall panels (including lintels and jambs), ring beams, floor and roof joists
- Design of the cantilever balconies
