Behavior of RBS Beams Reinforced by Stiffeners Subjected to Cyclic Loading
Journal of Engineering, 2018 This paper presents a numerical study of reduced beam section (RBS) beams with vertical and horizontal stiffeners. For RBS beams, it is speculated that strength deterioration will be caused by lateral buckling and local buckling.

Optimization of compressed stiffened flanges in bridge box girder cross section
Građevinar, 2017 Due to bending, flanges of steel box girder cross sections act as compression plates and require stiffeners. Using stability evidence from EN 1993-1-5, a parametric study was performed for six different types of stiffeners.

Strength of Steel Shell Cylindrical Panels Reinforced with an Orthogonal Grid of Stiffeners [PDF]
Journal of Applied and Computational Mechanics, 2022 The paper presents an approach to the strength analysis in steel cylindrical panels reinforced from the concave side with an orthogonal grid of stiffeners. A mathematical model of the Timoshenko (Mindlin – Reissner) type is used.

Application of superelements in static analysis of thinâ€walled structures
Journal of Civil Engineering and Management, 2004 A concept of a beam superelement is suggested as a new tool in the static analysis of structures made of thinâ€walled members. This proposal seems to be especially attractive for treating the problems where the existing oneâ€dimensional models do not ...

Structural analysis of long arm excavator boom for optimization performance under maximum breakout condition [PDF]
, 2020 Long Arm Excavators are widely used in the construction site for excavating deep holes or trenches. However, due to the often-severe work conditions, such as large lifting loads, poor ground conditions to sustain the machine’s self-weight, Long Arm ...

Optimum buckling design of composite stiffened panels using ant colony algorithm [PDF]
, 2010 Optimal design of laminated composite stiffened panels of symmetric and balanced layup with different number of T-shape stiffeners is investigated and presented. The stiffened panels are simply supported and subjected to uniform biaxial compressive load.

Dynamical analysis of multilayered reinforced composite cylindrical shells
Vietnam Journal of Mechanics, 2005 In the present paper the governing dynamical equations for multilayered reinforced composite cylindrical shells based on Kirchhoff-Love's theory and Lekhnitsky's smeared stiffeners technique are derived.

Hypertension, 2010 Aortic and large artery stiffening, hallmarks of vascular aging,1 are predictive of cardiovascular events, particularly in subjects with hypertension and components of the metabolic syndrome.2,3⇓ One hypothesis is that stiffening is a consequence of the combined insult of risk factors on the vascular wall.3 However, cross-sectional studies show little ...

BuildingsSteel beams with eccentric loads are subjected to combined bending and torsional moments that lead to lateral displacements, unwanted stresses at the top and bottom flanges, and global buckling along their length.
