Large Span Concrete Shell

In order to use the Rot-Up method of construction for reinforced barrel shell structures, the shell roof and the stiffening elements are cast on the ground and then lifted to the final position by means of rotations. This method of construction, when used for the construction of reinforced concrete shell structures, practically eliminates most of the formwork, scaffolding, working at elevation and use of heavy machinery. Furthermore, it makes it possible to cast sections that have low weight and high moment of inertia.
