ABSTRACT:
A lattice bridge construction system is characterised by the provision of lattice panels (A,B,C) which are of substantially identical length but of different depths relative to one another such that when variously combined one with another, with or without additional reinforcement, trusses having considerably more economic increments of bending strength may be achieved.
