<p>A method of fabricating a truss (12). The truss (12) including a bottom member (18) with at least one cable therein adapted for tensioning relative thereto, a top member (16) a first plurality of struts (20) and a second plurality of diagonal members (22). The method comprising the following steps: (a) connecting the ends of the top (16) and bottom (18) members; (b) connecting the struts (20) between the top (16) and bottom (18) members in a spaced apart relationship, the distance between the bottom end of the struts (20) along the bottom member (18) defining a pre-compressed distance; (c) connecting a pair of diagonal members (22) in between each adjacent pair of struts (20), between the top (18) and bottom (18) members; and, after steps (a) to (c); (d) increasing the tension in the cable(s) to reduce the length of the bottom member (18); and (e) adjusting the lengths of the diagonal members (22) and/or maintaining the pre-compressed distance between the bottom end of adjacent struts (20) at their connections to the bottom member (18) to respectively reduce and/or avoid any compressing or tensioning of the diagonal members (22).</p> |
