Ferrocement Shell Roof

Ferrocement is used to construct relatively thin hard strong surfaces and structures in many shapes such as hulls for boats shell roofs and water tanks.

Ferrocement shell roof.

Ferro cement can be modified to resist even high temperatures say 1200 c to 1500 c. Ferrocement fc is a form of thin shell construction that uses standard portland cement usually mixed with plaster sand. Effectively a series of. There will be no nuts and bolt arrangement as in the case of ac sheet metal frp roofs.

The computational design process consists of an integrated parametric model used for multi objective. 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. 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. Indian architecture studio wallmakers realizes its sculptural pirouette house in the center of india s urban and crowded city of trivandrum.

Approximately and ferrocement portal and purlins replacing ac sheets and structurals steel trusses and purlins. Therefore ferrocement buildings are. Unlike ac sheet metal frp roof all the ferrocement panels are joined monolithically. 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.

Ferro cement buildings are better pollution and fire resistant as compared to rcc. The ferrocement roof consists panels size 1 5mtrs x1 2mtrs. Reduced spacing yields uniform force dispersion and increases strength. These shell units are cast either manually on a masonry mould or mechanically on steel moulds.

Ferrocement originated in the 1840s in france and the netherlands and is the origin of reinforced concrete. 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. A barrel vault also known as a tunnel vault or a wagon vault is an architectural element formed by the extrusion of a single curve or pair of curves in the case of a pointed barrel vault along a given distance the curves are typically circular in shape lending a semi cylindrical appearance to the total design.
