A structural truss (11) has an upper chord (14) and a lower chord (15), bracing modules (16, 19) being secured between the upper and lower chords (14, 15), the bracing modules (16, 19) including a pair of braces, a first brace (16) of each pair on one diagonal of the truss (11) and the second brace (19) of each pair on an opposite diagonal and overlapping the first brace (16), the braces (16, 19) of each pair crossing at a point (23) intermediate of the upper and lower chords (14, 15), each bracing module (16, 19) being spaced along the truss (11) from the adjacent bracing modules (16, 19).
