On the evaluation of elastic critical moments in doubly and singly symmetric I-section cantilevers [PDF]
Journal of Constructional Steel Research, 2007 Abstract The so-called 3-factor formula is one of the most commonly employed general formulae to estimate the elastic critical moment of steel beams prone to lateral-torsional buckling. This work extends its domain of application to I-section cantilevers (i) with equal or unequal flanges, (ii) fully built-in or free to warp at the support and (iii ...

Mathematical Investigation of 1D Discontinuity Waves in Dilute Granular Gases
Mathematics, 2023 The propagation of acceleration waves in dilute granular gases was investigated. Acceleration waves propagating in elastic gases, mixtures, and other materials are widely studied in the literature, but not in granular gases.

Analysis of Dynamic Response and Ultimate Strength for Box Girder under Bending Moment
Journal of Marine Science and Engineering, 2023 The box girder can be seen as a kind of simplified ship structure that can withstand a vertical bending moment. Dynamic loads play an important role in structural safety analysis, such as ship bow slamming during harsh sea conditions.

Web rotational stiffness of continuous steel-concrete composite castellated beams
Fracture and Structural Integrity, 2019 Continuous composite beams can present a global instability known as lateral distortional buckling (LDB). The design code EN 1994-1-1:2004 provides a procedure for the verification of this ultimate limit state, in which the resistant bending moment is ...

Lateral distortional buckling of cellular composite-beams
Revista IBRACON de Estruturas e Materiais, 2018 In the region of negative bending moments of continuous and semi-continuous steel and concrete composite beams, the inferior portion of the steel section is subjected to compression while the top flange is restricted by the slab, which may cause a global
