One Gaudí beam and fabric formed shells

At the recent Structural Membranes conference in Stuttgart, Ronnie Araya presented a paper on the current research at CAST. This summer Ronnie and his crew have produced a number of shell structures in a sort of composite formwork created by tensioned sheets of fabrics and padded frc. The methods are low tech and fairly simple; the structures are effective in using only a minimum of materials to obtain structural properties; and the images of the structures are just beautiful.
