Abstract
A tension structure having a curved surface comprises a group of metal strips to form the curved surface and each of the strips is pre-stressed under tension for stabilizing the structure. The tension is produced in the strips by a group of tension members generally having a curvature opposite to that of the strips, the strips and tension members being arranged to effect tension indirectly on each other through an intermediate means such as a group of intermediate members disposed therebetween or air serving as the intermediate means or directly. In some instances, the ground surface regarded as having an indefinite radius is utilized as equivalent to the tension members. The erection of the structure is available by the application of tension and the conventional scaffold usually required may be omitted.
