Research ArticleOpen accessEvery word in the titleDesign of Multi-Layered Laminated Glass Beams in Lateral-Torsional BucklingGabriel Neves Alves FerreiraThis article proposes a methodology for the structural design of multi-layered glass beams considering lateral-torsional buckling. The basis is the use of two separate effective thicknesses to determine flexural and torsional rigidities, based respectively on the Enhanced Effective Thickness (EET) and sandwich theory. Analytical formulae are then used to calculate the elastic critical bending moment and a design curve is … …International Journal of Structural Glass and Advanced Materials Research, Vol. 6, Issue 1 · 25 Oct 2022 · 9,804 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTechnical Buckling, Stress and Strain Simplified Analysis of Semi-Slender Thin-Walled Cylindrical Pinned ColumnKrzysztof MurawskiThe stability of load-bearing members is a challenging issue for designers. The avoidance of possible stability troubles is a mandatory step of the overall design process. The paper presents and discusses two simplified methods based on the Technical Stability Theory (TSTh) of loss of stability of lateral buckling in elastic-plastic states of semi-slender columns axially compressed by force. It is … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 27 May 2021 · 6,823 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExperimental Comparison of the Known Hypotheses of the Lateral Buckling for Semi-Slender Pinned ColumnsKrzysztof MurawskiThe paper presents the comparison of experimental results obtained from tests on semi-slender columns with pinned ends made of steel R35 to simplifications and hypotheses of loss of stability by lateral buckling in elastic-plastic states of columns axially compressed by force. The Tetmajer-Jasiński’s and Johnson-Ostenfeld’s simplifications, as well as the hypotheses given by Engesser and Kármán and Shanley, Ylinen, Březina, … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 14 Apr 2021 · 6,411 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUncertainty Assessment for the Buckling Analysis of Glass Columns with Random ParametersMohammad Momeni, Chiara BedonLoad-bearing elements composed of glass, as known, are often susceptible to buckling collapse mechanisms. This intrinsic characteristic (and thus potential limitation for design) typically derives from the use of relatively small thicknesses to cover large spans and surfaces, thus resulting in a multitude of columns, beams, or plates that are characterized by high slenderness. In the literature, accordingly, several and … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 22 Dec 2020 · 6,295 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparison of the Known Hypotheses of Lateral Buckling in the Elastic-Plastic States of Thin-Walled Semi-Slender ColumnsKrzysztof MurawskiStability of structures, as known, is a challenging issue, especially in critical engineering, i.e., in designing structures which in a wrong design process could cause a catastrophe. The avoidance of possible stability troubles is mandatory. In this study, the simplifications and hypotheses of loss of stability by lateral buckling in elastic-plastic states of semi-slender columns axially compressed by force are … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 21 Dec 2020 · 6,252 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Unified Approach for the Shear Buckling Design of Structural Glass Walls with Non-Ideal RestraintsChiara Bedon, Claudio AmadioIn this study, a unified design approach is assessed and proposed for the shear buckling verification of structural glass walls supported by non-ideal restraints. Based on the current trends of practice in buildings, the effect of (i) adhesive joints, (ii) metal frames with interposed adhesive joints or (iii) point mechanical connectors on the actual shear buckling behavior of the examined … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 22 Jan 2016 · 8,287 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReliability Assessment of Buckling Strength for Compressed Cylindrical Shells with Interacting Localized Geometric ImperfectionsJalal El Bahaoui, Abdellatif Khamlichi, Larbi El Bakkali, Ali LimamProblem statement: Elastic cylindrical shells are common structures in the fields of civil engineering and engineering mechanics. These thin-walled constructions may undergo buckling when subjected to axial compression. Buckling limits to large extent their strength performance. This phenomenon depends hugely on the initial distributed or localized geometric imperfections that are present on the shell structure. Localized geometric imperfections result in … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 8,320 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNumerical Study of Post-Buckling of Clamped-Pinned Pipe Carrying Fluid Under Different ParametersDahmane Mouloud, Samir Zahaf, Mawhoub Soubih et al.This research aims to calculate the first three natural frequencies and critical velocity of a fluid-conveying pipe are obtained with numerical approach with standard finite element method and this by discretizing the structure wall and internal flow, starting from beam type with two degrees of freedom per node.

Research ArticleOpen accessIn the keywordsEffect of Two Interacting Localized Defects on the Critical Load for Thin Cylindrical Shells Under Axial CompressionAbdellatif Khamlichi, Jalal El Bahaoui, Larbi El Bakkali et al.Problem statement: Many modern structures are made from thin shells. Design of these elements depends to a large extent on their buckling behavior which is hugely affected by the initial geometric imperfections. Approach: For axially compressed isotropic circular cylindrical shells, axisymmetric localized geometric imperfections were found to reduce severely the buckling strength. Among various axisymmetric shapes of localized defects that … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,065 accessesView PDFCite
