Abstract

Corrugated steel web composite box girder is a new type of steel-concrete composite structures, and it replaces the traditional one with corrugated steel webs and has the characteristics of both concrete and steel webs. The thesis summarizes the research status and results of fatigue property of composite box girder with corrugated steel webs and finds a number of structural fatigue properties that have a significant impact on the factors. Through analysis, this paper presents the prospects of further research of fatigue property in composite box girder with corrugated steel webs and applications of fatigue characteristic analysis in the construction of composite box girder with corrugated steel webs in future. The results show that the fatigue life evaluation method of corrugated steel web composite beam based on fatigue reliability theory should be developed, and the anti-fatigue design of bridge suitable for our national actual situation should be explored, suggesting for bridge construction.
