Fire load-bearing capacity specified for columns made of stainless steel of selected types – comparative analysis

<ns3:p>The load-bearing capacity specified for flexural buckling and related to fire conditions was precisely determined. It was identified for corresponding columns with identical geometry and support method, made of stainless steels of various types, with differentiated crystal structures. For comparative purposes, the obtained results were referred to the analogous load-bearing capacity of the same columns, designed this time from non-alloy structural steels of selected types, associated with the previously considered stainless steels due to their similar strength. It was shown that the internal structure of a stainless steel determines its fire resistance. In general, however, this resistance is significantly higher in relation to that which characterizes the typical non-alloy structural steels.</ns3:p>
