ABSTRACT:

To investigate the remaining compressive capacity and the prospective behavior mode of corroded H-shaped column under axial compression, numerical simulations are carried out. Four main parameters that affect the capacities of columns are considered including: (1) reduction degree of cross-sectional area, (2) extent of corrosion, (3) slenderness ratio of column and (4) location of corroded region. The research indicates that one parameter alone is not enough to characterize the corrosion and take into consideration the effect of corrosion on the remaining capacity of column. The experimental results were compared with the axial capacities predicted by the current design specifications. The effective width method recommended by AISI-EWM provides more reasonable prediction for the capacity of deteriorated columns. On the basis of research, simplified design method ‘Modified Minimum Section Method’ (M-MSM) and formulas are proposed for the prediction of the remaining compressive capacity of H-shaped column.
