A Review Paper on the Fatigue of Steel Bridges
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
Steel bridges plays an important role in the transportation industry, they are preferred for their ease in construction, maintenance and strengthening capabilities. Steel bridges are serving transportation industry since many decades. Majority of the bridges have completed significant design life, in addition to this there is significant increase in the traffic intensity and the axle loads. Many incidents all over the world have reported cracks in the main members. The primary reason was identified as fatigue, which can trigger at working load. Factors like corrosion, impact loads are acting as a catalyst for the process of fatigue failure. Hence all over the world many attempts have been taken up to determine the residual fatigue life of the existing steel bridges with a due consideration to the increased traffic intensity. In addition to this design guidelines have also been given attention to incorporate the effects like increased traffic intensity, corrosion etc. The present paper focuses on the review of the literature for fatigue analysis of the steel bridge.
