Book Description
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.

Book Description
This study has introduced a method for fatigue performance evaluation of steel orthotropic bridge decks based on filed measurements for hotspot stress. The long-term stress of the orthotropic bridge deck of Jinchang Road Canal Bridge in Hangzhou, China, was observed by sensors. The fatigue damage and fatigue reliability of the bridge deck were analyzed and evaluated according to the stress. The results show that: (a) the fatigue life of the bridge deck is larger than the design value, indicating that the design of the orthotropic bridge deck is reasonable; (b) the fatigue loads acting at three hotspots can be described by normal distribution; and (c) for the current traffic volume, the fatigue reliability index of the three hotspots is greater than two in the design period. The fatigue reliability index of the three hotspots decreases significantly with the increase of traffic flow, at which time the fatigue damage becomes considerable.

Book Description
This book provides a basis for the design and analysis of welded components that are subjected to fluctuating forces, to avoid failure by fatigue. It is also a valuable resource for those on boards or commissions who are establishing fatigue design codes. For maximum benefit, readers should already have a working knowledge of the basics of fatigue and fracture mechanics. The purpose of designing a structure taking into consideration the limit state for fatigue damage is to ensure that the performance is satisfactory during the design life and that the survival probability is acceptable. The latter is achieved by the use of appropriate partial safety factors. This document has been prepared as the result of an initiative by Commissions XIII and XV of the International Institute of Welding (IIW).

Book Description
Over the past 20 years, the Transport and Road Research Laboratory has carried out a co-ordinated programme of fatigue testing, including work on the fatigue performance of reinforced and pre-stressed concrete beams. The research has led to a better understanding of the fatigue behaviour of plain concrete, the various types of reinforcing bars in air and concrete, continuous welded, lapped and coupled bars, and the effects of corrosion. The work of TRRL and many other organizations is reviewed and a summary of current design rules with recommendations for assessing the fatigue life of new structures in service is given.

Book Description
"This book emphasizes the physical and practical aspects of fatigue and fracture. It covers mechanical properties of materials, differences between ductile and brittle fractures, fracture mechanics, the basics of fatigue, structural joints, high temperature failures, wear, environmentally-induced failures, and steps in the failure analysis process."--publishers website.
