This paper presents a numerical study on the behaviour of carbon steel and stainless steel I-beams subjected to lateral-torsional buckling (LTB) in case of fire. The main motivation for this work is the fact that part 1-2 of Eurocode 3 (EC3) does not take into consideration the beneficial effect, resulting from the reduction of the plastic zones connected with non-uniform bending diagrams along the beam. Although new formulae for the LTB, that approximate better the real behaviour of steel structural elements in case of fire, have been proposed in previous works, they still do not considered the combination of end moments and transverse loads, as it is stated in part 1-1 of EC3. Therefore, in this paper numerical simulations, of steel beams with combined end moments and transverse loads, are compared with the LTB design curves of EC3, and new correction factors that improve these curves are presented.

Stainless steel beam-columns in case of fire

in Beale, R. G. (Ed.) proceedings of the 6th International Conference on Steel and Aluminium Structures ICSAS'07 (2007, July 25)

Eurocode 3 states that stainless steel structural members, subjected to high temperatures, must be designed with the same expressions used on carbon steel members. However, as these two materials have ... [more ▼]

Eurocode 3 states that stainless steel structural members, subjected to high temperatures, must be designed with the same expressions used on carbon steel members. However, as these two materials have different constitutive laws, it should be expected that different formulae for the calculation of member stability should be used for room temperature design. In a recent work, the authors have proposed a more accurate procedure for the evaluation of the fire resistance of stainless steel columns which necessarily affects the beam-column design formulae. This work presents a numerical study of the behaviour of stainless steel beam-columns subjected to fire. [less ▲]

Lateral-torsional Buckling of Ferritic Stainless Steel Beams in Case of Fire

in Proceedings of the first International Conference on the Art of Resisting Extreme Natural Forces (2007, July 12)

This work presents a numerical study of the behaviour of ferritic stainless steel Ibeams subjected to lateral-torsional buckling and compares the obtained results with the beam design curves of Eurocode 3. New formulae, for the lateraltorsional buckling, that approximate better the real behaviour of ferritic stainless steel structural elements in case of fire are proposed. These new formulae were based on numerical simulations using the program SAFIR, which was modified to take into account the material properties of the stainless steel. [less ▲]
