Abstract

This paper study the process and characteristics of the bridge structure steelQ420qE fatigue crack prefabricated. The results provide an experimental base and computing foundations for the bridge This paper studies the Crack tip opening displacement fatigue precracking experiment on steel Q420qE. The experiment respectively tested of Fatigue crack growth of base material, heat-affected zone ,Weld seam, whose results are analyzed, and the corresponding conclusions were studied.
