Abstract: A method of building a structure, the method including the steps of: 1. fabricating a generally longitudinal, non-steel sub-structure of the structure with a cable retainer attached to, or forming part of, the sub-structure and that extends substantially longitudinally therealong; 2. assembling the sub-structure into a structure; 3. inserting a cable into the cable retainer; 4. after step 2, applying a tensile force to the cable relative to the cable retainer; and 5. after step 4, bonding the cable to the cable retainer.

Abstract: A domed roof structure may include a plurality of generally rectangular roof members each including an upper surface; a lower surface; a pair of first opposed side surfaces and a pair of second opposed side surfaces, each diverging from the upper surface to the lower surface; a first passage from one to the other of the pair of the first side surfaces; and a second passage from one to the other of the pair of the second side surfaces. A first cable may pass through the first passages in adjacent said roof members; and a second cable may pass through the second passages in adjacent said roof members. Applying tension to the cables may drive the end faces of adjacent said roof members towards each other thereby increasing the angle between adjacent said roof members so as to form a domed roof structure.

The roof structure (10) also includes: a first cable (28) passing through the first passages in adjacent said roof members; and a second cable (29) passing through the second passages in adjacent said roof members.

Abstract: A domed non-steel roof frame (12). The frame (12) has at least three corners and an outwardly convex shape with an uppermost apex (20). The frame (12) comprises at least three non-steel interior members (18), at least three interior cable retainers and at least three interior cables. The at least three non-steel interior members (18) each extend from one of each of the corners to the apex (20).
