BRIDGE LOAD CAPACITY, RATING AND POSTING. NEW ZEALAND ROADING SYMPOSIUM 1987. VOLUME 4

It has been shown by numerous destructive tests that the actual load carrying capacity of a bridge is almost always greater than would be calculated from a traditional analysis. This is due mainly to (a) material strengths usually being significantly greater than specified values; (b) structures having more redundancy than is traditionally assumed; and (c) non-structural members contributing significantly to strength. This paper discusses procedures for assessing bridge capacity, both for overloads and for normal loads, by taking account of the above, to arrive at a safe and realistic value of load capacity. By doing so, the maximum economic benefit will be obtained from the existing investment. For the covering abstract of the symposium see IRRD 810782. (Author/TRRL)
