REPAIR OF STEEL TRUSS BRIDGES

Through-truss bridges are susceptible to damage from collision from vehicles, or their loads, which are being carried through the trusses. In this paper, (paper 7) case histories of three instances of damage to steel through- truss bridges on major coastal highways in new south wales are described. Considerations with regard to the requirements for temporary repairs, with use by one or two lanes of traffic, and permanent repairs, are discussed. Methods of repair are described. The need for quick availability of information about forces in truss members, for various loadings, is pointed out. Requirements for protection of truss members are noted. (a) (TRRL)
