Experimental and numerical evaluation of inelastic lateral-torsional buckling of I-section cantilevers

A Review on Comparison of RCC and Steel Multistorey Building with and Without Beam Projections

“…The test specimens had rotational angles that ranged from 7.42 to 17.98, with a maximum recorded of 11.77, a torsional angle that was deemed relatively high. [7] Yoshihiro Kimura, et.al (2021) studies based-on flange-web interaction, the I-beam cantilevers' elastic local buckle strength when subjected to shear force and bending moment. Local buckling is a type of loss in which the cross-sectional form of the beam is altered without causing a twist about its axis or a beam's change geometry, such as horizontal displacement.…”

Equivalent imperfections for the out-of-plane stability design of steel beams by second-order inelastic analysis

“…Although the aforementioned beam FE modelling approach has been successfully employed in numerous previous investigations [10,11,13,45,57], in the present study, prior to being used to generate benchmark data, the approach is further validated against the results from 44 experiments reported in the literature [60][61][62][63][64][65], focusing on beams experiencing LTB. The loading configurations included (i) 3-point bending and 4-point bending [60], (ii) 3-point bending with eccentrically applied vertical loading, leading to additional torsion [61][62][63][64] and (iii) concentrated loading applied at the free-end of cantilever beams [65]. The boundary and loading conditions of the beam FE models were consistent with those employed in the tests.…”

Out-of-plane stability design of steel beams by second-order inelastic analysis with strain limits

“…The shell FE models developed in this study were validated against the results from 59 experiments on beams experiencing LTB collected from the literature [62][63][64][65][66][67][68][69]. The loading configurations included (i) 3-point bending and 4-point bending [62], (ii) concentrated loading applied at the free-end of cantilever beams [63,64] and (iii) 3-point bending with eccentrically applied vertical loading, leading to additional torsion [65][66][67][68][69]. The boundary and loading conditions employed in the tests were replicated in the FE models.…”
