In-plane structural response and design of steel I-section beam-columns at elevated temperatures

In this paper, the behaviour and design of steel I-section beam-columns in fire are explored. Finite element models capable mimicking developed. Results from experiments on literature utilised for validation finite models. Extensive structural performance data generated response through numerical simulations, considering different cross-section shapes, elevated temperature levels, member slendernesses loading conditions. The accuracy safety beam-column methods provided current European standard EN 1993-1-2 its upcoming version prEN A new method that is compatible with room 1993-1-1 put forward. proposed rules enable establishment a consistency between standards (i.e. 1993-1-2), which currently lacking. higher accuracy, reliability relative to those given prEN1993-1-2 verified.
