Ferrocement Shell Roof

Mmt ferrocement shells these wafer like structures are steel reinforced arched shells with effective thickness of 2 5cm and they take equal load of respective r c c slabs.
Ferrocement shell roof. There will be no nuts and bolt arrangement as in the case of ac sheet metal frp roofs. Ferrocement originated in the 1840s in france and the netherlands and is the origin of reinforced concrete. Ferro cement buildings are better pollution and fire resistant as compared to rcc. The ferrocement roof consists panels size 1 5mtrs x1 2mtrs.
The barrel vault is the simplest form of a vault. Therefore ferrocement buildings are. This paper describes the geometry and structural design of a cable net and fabric formed ferrocement sandwich shell roof as part of the nest hilo project to be built in dübendorf switzerland in 2016. The dwelling constructed of undulating brickwork is.
Effectively a series of. Ferro cement can be modified to resist even high temperatures say 1200 c to 1500 c. Ferrocement channel roof provides light weight roofing 60 reduction in dead weight as compare to rcc pre casting of roof leads to substantial reduction in construction time. Compared to traditional construction the cement is reinforced with more steel or fiber at a closer spacing.
Ferro cement is a very good fire resistant material having capacity to resist fire up to 750 c for long period of 48 hours and even more. Unlike ac sheet metal frp roof all the ferrocement panels are joined monolithically. The computational design process consists of an integrated parametric model used for multi objective. Approximately and ferrocement portal and purlins replacing ac sheets and structurals steel trusses and purlins.
Reduced spacing yields uniform force dispersion and increases strength.
