Structures, facades, and fire safety in multi-storey car parks
The use of high strength steel for columns permits a reduction of their size and cladding has to ensure optimum ventilation, an essential fact when calculating fire safety. Natural light is a key element for the users' comfort and perception of space but also crucial for the building's energy consumption. A car park is subjected to many functional requirements, but at the same time architectural aesthetics are becoming more and more important.Article
Cofraplus® 220 combines the outstanding resistance of the patented steel profile with the performance of a ribbed reinforced concrete slab. The total load bearing capacity results as the sum of the resistance of both elements as no composite action is taken into account.
The high values of the moment of inertia and the bending moment guarantee large span without propping.
Cofraplus® 220 sheets are available with thicknesses of 1.13 mm and 1.25 mm with a maximum length of 9 m.
