Abstract
Steel structural members in different application areas may be subjected to localized flame impingement instead of flashover scenario due to several reasons. Though extensive research has been performed to study component level systems in conventional fires (ISO 834, ASTM E119, other parametric fire curve), the behavior of beam column rigid connection in localized fire is still not investigated in details. To understand the behavior of beam-column connection under localized fires, the present paper deals with a detailed numerical investigation of the behavior of a moment resisting frame (MRF) assembly with fully welded beam column connection in terms of connection rotation and forces under different positions of localized fire source underneath the exposed beam. For fire scenarios where the frame survived during the entire duration of fire, the post fire rotation of the connection located at far end from the fire source was found to be higher than the near end. Secondly, for cases where the frame failed, it was observed that for identical strength of weld and base material, failure is likely to initiate at the weld line connecting the bottom flange of the beam located at far end from the fire source. Finally parametric studies were performed with different weld sizes and it was concluded that size of weld has significant effect on increasing the joint survival time for MRF exposed to localized fire.
