Research Progress on Fatigue Reinforcement of Orthotropic Steel Deck

Abstract

In view of the currently widely-used orthotropic steel deck (OSD), the problems of fatigue damage of the bridges are summarized based on the analysis of OSD fatigue damage of the related research results. From two aspects: local reinforcement measures and integral reinforcement measures, this paper discusses the principles of some techniques in this field, as well as the existing advantages and deficiencies of each technique. This paper also provides suggestions and directions for future research: To establish and improve the industry standards of OSD fatigue, which is conducive to the innovation and development of related technologies; Multidimensional cooperation associated with other fields is conducted to explore new ideas and technologies for fatigue damage reinforcement of OSDs.
