ANALYTICAL INVESTIGATION OF INFLUENCE OF CORROSION DAMAGE POSITION ON RESIDUAL BENDING CAPACITY OF STEEL PIPE PILE

Abstract

In this research, a residual loading capacity of corroded steel pipe pile was investigated by FE analysis. According to the analysis results, although the effect of eccentricity for a residual thickness was not so high, the damage location and distribution had a profound influence on the loading capacity. In addition, a position of damaged steel pipe pile contributed little to the loading capacity in both 2-D and 3-D frame models. However, in the case of 3-D frame model, the capacity decreased when the loading position reaches the deck edge.
