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 titleOptimization of Reinforced Concrete Beams and Steel Beams: A Comparative StudyJoel M. Ozimboski, Zacarias M.C. Pravia, Moacir KripkaIn order to support the structural designer with regard to the selection of structural materials, this work presents results obtained from the optimization of reinforced concrete beams and welded “I” steel beams. To achieve this objective, both problems were formulated according to Brazilian standards, considering the cost as objective function and section dimensions as design variables. For the optimization of … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 18 Jun 2020 · 6,596 accessesView PDFCite

Research ArticleOpen accessEvery word in the titlePhotocurrent and Photoluminescence Investigations of GaInNAs and GaInNAs(Sb) Quantum Wells Grown by Molecular Beam EpitaxyS. Ben Bouzid, F. Bousbih, A Hamdouni et al.We have investigated photocurrent (PC) and photoluminescence (PL) in sequentially grown GaInNAs/GaAs and GaInNAs(Sb)/GaAsSbN quantum wells. Photocurrent transitions are analyzed by theoretical calculations using envelope function formalism taking into account the strain effect and the strong coupling between nitrogen localized state and the GaInAs band gap. The results are consistent with a type I band alignment and a conduction band … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,475 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNumerical Study on Coupling Beam Retrofitted Using CFRP and GFRP SheetsSaeideh Hakimi, Rahmat MadandoustOne of the most useful way to resist against earthquake is using coupling beam of steel shear walls. The steel shear wall’s behavior depends on several factors such as stiffness, ductility, strength and so on. But, it has the shear cracks in coupling beam. In this paper, the effect of Carbon Reinforced Fiber Polymer (CFRP) on coupling beams has been … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 3 · 6 Aug 2018 · 7,723 accessesView PDFCite
