The majority of fatigue damage cases that have been reported for steel and composite bridges were generated by “secondary” effects that were unforeseen or overlooked in the design of these structures
The majority of fatigue damage cases that have been reported for steel and composite bridges were generated by “secondary” effects that were unforeseen or overlooked in the design of these structures. These effects are often the result of improper detailing and inadequate idealization of the behaviour of steel bridge details.
This volume presents a catalogue of more than 100 fatigue damage cases in steel and composite bridges. These cases are categorised based on detail type and the mechanisms behind fatigue damage are presented and discussed.
The book aims at promoting good design practice and thereby ensuring adequate fatigue performance of steel and composite bridges.
