Publisher's Synopsis
A broadly-based research programme on orthotropic steel bridge decks, led by D.E. Nunn, was carried out between 1963 and 1987 covering traffic usage, surfacing and fatigue. Initially the work was predictive, determining the main variables and establishing the basis of a fatigue assessment methods. Following the discovery of fatigue cracks in service, methods of repair and strengthening were developed. This work has been recorded in internal reports, but much of it has not been generally available until publication of this review. Experimental results are presented and recommendations given for the fatigue classification of welded joints in orthotropic decks.
