- Abstract
- The primary objective of this study is to evaluate the fire resistance performance of steel columns with removed or reduced flange Spray-applied Fire Resistive Material(SFRM). The finite element analyses were performed to examine the fire load behavior of steel columns (H-300x300x10x15) with damaged SFRM subjected to concentric axial compression. Moreover, heat transfer analysis was conducted to predict the temperature distribution in the steel columns under the action of the ISO834 curve.
Structural analysis is then carried out to elevate the influence of temperature on column axial load behavior.
It also is shown 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 indicate 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.
