Abstract: A simple analytical approach based on the Rankine principle has been developed to determine the ultimate resistance of steel frames in fire. The proposed Rankine approach gives an approximation of the frames' fire resistance ...

Abstract: A simple and direct analytical formula has been derived to determine the compressive resistance of steel columns subjected to fire conditions. The approach is based on the Rankine principle, which allows the strength and ...

Abstract: This paper presents a second-order elastic-plastic hinge method and a finite-element model for the analysis of plane frames in fire. Both methods are derived from the same two-node corotational beam element and are based ...
