ABSTRACT:
A roof structure consisting of a thin curved slab of reinforced concrete which is initially cast by conventional techniques as a flat slab, tension cables (preferably of high tensile steel) extending in one or more directions being arranged across the slab and being connected to opposite edges of the slab and also connected to the slab at points along their lengths by means of tensioned hangers or compression props or columns of predetermined lengths, tension then being applied to the cables to cause them to straighten and in so doing to cause the concrete slab to take up a curved shape so as to form a shell structure which resists applied loads by reason of its curved shape.
