Current practice in steel building construction mainly includes the use of fire protection materials such as spray-applied fire resistive material (SFRM) to thermally protect structural steel columns from fire. During construction or occupancy, the SFRM may become damaged. A steel column with damaged SFRM may exhibit reduced structural performance defects due to the effects of elevated temperature during fire events. Thus, the fire load behavior of steel columns with removed or reduced SFRM needs to be examined to predict the structural damage by fire.This paper performed to evaluate the fire resistance performance of steel columns with removed or reduced SFRM. The finite element analyses will be performed to examine the fire load behavior of steel columns (H-300x300x10x15) with damaged SFRM subjected to concentric axial compression. Heat transfer analysis will be performed to predict the temperature distribution in the steel columns under the action of the ISO834 curve. Structural analysis will then be performed to elevate the influence of temperature on column axial load behavior.It was found that the complete removal of even a relatively small patch of SFRM led to dramatic rise of temperature at any given fire duration, and led to significant reduction of the axial load resistance of the column.In this study, the results of analysis show that even small remnants of SFRM led to an effective reduction of temperature at any given fire duration, and improved significantly the axial load capacity of a column as compared to the complete removal cases of SFRM.
