Elastic critical moment for bisymmetric steel profiles and its sensitivity by the finite difference method [PDF]
International Journal of Applied Mechanics and Engineering, 2016 It is widely known that lateral-torsional buckling of a member under bending and warping restraints of its cross-sections in the steel structures are crucial for estimation of their safety and durability. Although engineering codes for steel and aluminum

Elastic Critical Moment for the Lateral-Torsional Buckling (LTB) Analysis of Structural Glass Beams with Discrete Mechanical Lateral Restraints. [PDF]
Materials (Basel), 2020 Structural glass beams and fins are largely used in buildings, in the form of primary load-bearing members and bracing systems for roof or facade panels. Several loading and boundary conditions can be efficiently solved by means of bonded composites that

Novel formula for the elastic critical moment of beams with corrugated web
ce/papers, 2023 AbstractThis paper presents a novel analytical expression to determine the elastic lateraltorsional buckling resistance of I‐beams with corrugated web. The corrugated web beams have higher torsional stiffness than the flat web beams; therefore, the self‐weight of the beam can be reduced. The appropriate hand calculation methods to determine the elastic

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.

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

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 ...

A new expression to predict secant rotational stiffness of spudcan in undrained soils [PDF]
E3S Web of Conferences, 2021 The nonlinear behavior of spudcan foundation will lead to the decrease of the rotational stiffness of the spudcan, leading to the increase of the stress at the critical member of the offshore jack-up drilling platform. Secant rotational stiffness is used
