Fatigue is an important issue for steel and composite railway bridges since they endure million stress cycles during their life. Past studies assessed fatigue resistance of bridges providing the basis for current codes, even if many important factors are not actually covered: in particular fatigue effects due to vibrations and distortions. The project aims to develop a procedure to evaluate structural integrity and remaining fatigue life including vibration/distortion induced effects. To this purpose improved representation of traffic loads and enhanced experimental/numerical techniques will be adopted.

Abstract

Fatigue is an important issue for steel and composite railway bridges since they endure million stress cycles during their life. Past studies assessed fatigue resistance of bridges providing the basis for current codes, even if many important factors are not actually covered: in particular fatigue effects due to vibrations and distortions. The project aims to develop a procedure to evaluate structural integrity and remaining fatigue life including vibration/distortion induced effects. To this purpose improved representation of traffic loads and enhanced experimental/numerical techniques will be adopted.
