초록

In this study, the changes in compressive strength of steel tubular short columns with local corrosion is investigated using a finite element approach. The dimensions of the local corrosion are defined by its depth (0, 1.5, 3, 4.5 and 6 mm), height (0, 20, 40, 60, 80, 100, 120, 140, 160 and 180 mm), circumference (0, 90, 180, 270 and 360°) and location of damage along the steel tubular short column. There are 42 finite element models executed in this study that are categorized as Type A, Type B and Type C specimens. The results of the finite element models were compared against the previous experimental tests for model validation. Moreover, a parametric study was used to study the effect of the corrosion depth, height and circumference to the compressive strength of a steel tubular short column. Comparing the results of the finite element analysis, experimental and calculated compressive strengths, the percentage error is found to be within 10%.
