Traditional buildings typically utilize a box or shear structural systems. Such systems concentrate forces at connections between members often occurring at right angles. This represents one of the least effective structural systems1. By contrast thin shell concrete dome structures distribute forces along their entire envelope2. In this highly efficient structural system, forces are transferred gradually and evenly to the foundation along the entire building perimeter.
Furthermore, domes typically act in compression and concrete is known to be highly efficient in compression. The efficient use of materials and highly efficient structural system, make Binishells stronger both in symmetrical loading (ie. earth berming) and asymmetrical loading (ie. high wind or earthquake). Additionally, Binishells are inherently aerodynamic making them highly effective in high winds or floods. The non-flammable nature of concrete and their natural aerodynamics also make Binishells highly resistant to fires.
