Research ArticleOpen accessIn the keywordsStatic and Dynamic Performance Improvement of Conventional Computer Numerical Control Machine Tool Bed with Hybrid Welded SteelS.S. Abuthakeer, P.V. Mohanram, G. MohankumarProblem statement: The advancements in machine tools to maximize the production by increasing spindle speeds have caused vibration in machine tools. The two functional requirements of machine tool bed for machine tools are high structural stiffness and high damping, which cannot be satisfied simultaneously if conventional metallic materials such as cast iron are employed. Hence there is a need to … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 11,479 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsCost Optimization of Composite I Beam Floor SystemUroš Klanšek, Stojan KravanjaThe paper presents the cost optimization of the composite I beam floor system. The composite I beam floor system is designed to be constructed up of a reinforced concrete slab and doubly-symmetrical welded steel I beams. The optimization was performed by the nonlinear programming approach, NLP. An accurate objective function of the manufacturing material, power and labour costs was developed … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 7,435 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptimization 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 PDF Cite

Research ArticleOpen accessAll words, across the recordWelded Connections of Wind Turbine Towers under Fatigue Loading: Finite Element Analysis and Comparative StudyNafsika Stavridou, Evangelos Efthymiou, Charalampos C. BaniotopoulosIncreased contemporary energy needs have led to multiple investments on wind power plants and structural improvements are considered necessary for the construction of taller, more robust and more economical structures. Tubular steel wind turbine towers that are the prevailing structural configuration, demand welding of circular subparts to construct the tower structure. These circumferential welds between tower subparts and between the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 18 Aug 2015 · 8,894 accessesView PDF Cite
