EFFECT OF WELD DEFECT ON THE PERFORMANCE OF STEEL PIPE PILES WITH A WELDED JOINT SUBJECTED TO IMPACT LOADING
Most of steel structures, such as steel pipe piles, etc., are joined by welding. During welding, various weld defects such as cracks, undercuts, misalignments, etc, are caused due to the incomplete fusion and the imperfect shape in welds. It is therefore necessary to investigate the effect of undercuts and welding residual stress on the behavior of steel structures. In this paper, the effect of weld defect(undercut) on the performance of steel pipe piles with a welded joint under impact loading was investigated by three-dimensional elastic-plastic finite element analysis. It is seen from analysis results that maximum load carrying capacity of steel piles undercut decreases due to influence of undercuts.
