Huddle Carl F: Arch supported membrane structure. Vredevoogd Jon, Tension Structures Co, October 7, 1975: US3909993 (24 worldwide citation)

A pre-stressed arch supported membrane structure, a method of assembly and erection and a means of tensioning a membrane of double curvature supported by and attached to upright arches.By moving the ends of flat resilient arch structural members closer together, pre-stressed arches are formed by 'bo ...

Carl F Huddle: Laminated arch members and method of constructing them. Tension Structures Co, Jon D Vredevoogd, June 6, 1978: US04092992 (24 worldwide citation)

Large hollow curved beams and arches are inexpensively produced by curving individual shallow components, such as channels, that are then tiered to form a large laminated member. Smaller beams or arches can be made by tiering the components, curving them all at one time, then fastening them together ...

Huddle Carl F: Tension Structures Co, Baillio A F, April 9, 1974: US3802450 (17 worldwide citation)

A tent-like structure, hereinafter called a 'pavilion,' which includes two more or less upright arches which are mounted with their legs near but may be spaced from each other to provide for ventilation, another arch on each side of the upright arches which is inclined away from them, and a membrane ...

Carl F Huddle: Tension Structures Co, May 4, 1976: US03953955 (15 worldwide citation)

A tent-like structure, hereinafter called a vaulted membrane structure that has a series of curved arches and a panel of flexible covering material attached to and tensioned between each pair of arches. In one embodiment, the arches on each side of an intermediate portion of the pavilion are mounted ...
