Abstract : The patent relates to a self-erecting structure including a plurality of trusses joined by cables with a hydraulic system for producing relative rotation of the trusses at their juncture axes. The trusses comprise series of subelements hinged at common juncture I-beams. The cables effectively join adjacent structural subelements and the hydraulic system includes a plurality of hydraulic elements having their outer casings secured to the I-beams and their piston elements extending downwardly against the cable. Upon the application of hydraulic pressure, the outer casing and juncture I-beams move upward in opposition to the restraint of the cables causing relative rotation at the junctures of adjacent trusses to the desired angular position thereby producing an arch bay section. The curved edges of a series of arches are connected together to form the self-erecting structure.
