The Bidge, with 17meters span, has got the shape of a tube. This system concept is based on the idea
that a building can be designed to resist lateral loads by designing it as a hollowcantilever perpendicular
to the ground. In the simplest incarnation of the tube, the perimeter of the exterior consists of closely
spaced columns that are tied together with deep spandrel beams through moment connections. This
assembly of columns and beams forms a rigid frame that amounts to a dense and strong structural wall
along the exterior of the building.
