Origami-based folded structures and prestressed
sandwich shell beams
Concrete light –
As a result of their spatial load bearing behaviour, shell structures provide high load-carrying capacity whilst being very slender and lightweight, especially if membrane action is activated in compression. It is especially the fact that concrete is freely moldable in its fresh state that enables the production of a wide range of geometries. In the past few years, however, the exceedingly high cost of complex formwork designs and the susceptibility to corrosion of the steel reinforcement of slender concrete structures largely restricted the manufactured range to straight, planar elements with...
