ABSTRACT:
A lattice panel (P1) for a bridge has only a single chord (C1), along one side (S1), with no chord along the opposite side (S2), resulting in a cost and weight saving when two such panels are stacked in one plane. A lattice (L) of web members (W) comprises: either n+1 perpendicular web members (Wp1-3) at n+1 "first" nodes (N1. 1-N1.3) or n perpendicular web members (Wp1, Wp2) at all but an end one of n+1 "first" nodes (Wp1, Wp2); 2n "first" oblique web members (Wo1-Wo4) and 2n "second" web members (Wo5-Wo8) form two quadrilateral structures between the n+1 "first" nodes (Wp1, Wp2). Two "fourth" nodes (N4.1, N4.2) are formed by the tops of the quadrilateral structures, for connection to a second chord or to corresponding nodes of a like panel.
