Research ArticleOpen accessIn the abstractCost 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 PDFCite
Research ArticleOpen accessIn the abstractBending Moments Distribution at the Main Structural Elements of Skew Deck-Slab and Their Implementation on Cost EffectivenessMaher KakishThe distribution of bending moments in T-beam deck slab varies from one T-beam to another. The design of T-beams should be based on the actual bending moments each beam is subjected to for the purpose of achieving economy especially in bridge deck slab, extended over big area. The saving in some cases is substantial due to reducing the quantities of … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,596 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element and Experimental Serviceability Analysis of HSC Beams Strengthened with FRP SheetsSeyed Hamid Hashemi, Reza Rahgozar, Ali Akbar MaghsoudiThe use of externally bonded composite sheets or laminates is by now a diffuse technique to strengthen existing RC structures. However, some aspects of flexural condition still need experimental and numerical analysis; furthermore, especially for serviceability checks, there is a lack of code provisions. Six reinforced high strength concrete (HSC) beams strengthened with FRP sheets were fabricated and tested, the … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 7,440 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a Wear Map for the Sliding and Rotational Wear behavior of ShaftsAl-mahasne Mayas MohammadThis study was an attempt to study the wear calculation method for rotating shaft in the friction couple type shaft-cuff in conditions of oiling in high dusty environment. The size and quantity of abrasive particles that go into the clearance between friction surfaces, definition of the pressure including the load in conjugate that is given by the cuff spring as … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 6,913 accessesView PDFCite
Research ArticleOpen accessIn the abstractUpgrading of Light Dewaxed Oil through Hydrofinishing and Additives Blending for Producing Automatic Transmission FluidGamal Abdel-Nasser Gohar, Mohamed Sherif El-Gayar, Abd El-Moneim Ibrahim et al.Light dewaxed oil was produced through dewaxing process of the light waxy distillate raffinate of crude oil from Western Desert of Egypt using methyl ethyl ketone/toluene mixed solvent. Hydrofinishing process was used to remove the non-hydrocarbon constituents and to improve the physicochemical properties of the produced oils such as color, viscosity index, inhibition responses, oxidation and thermal stability. The operating … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 6,976 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Functionality of Fiber Bragg Grating Sensor Compared to that of Foil GaugeBashir Ahmed Tahir, Jalil Ali, Rosly Abdul RahmanTechnology such as Fiber Bragg Grating (FBG) sensors are widely accepted in almost all industries. FBG are being investigated for their applicability in other markets such as smart structures. Fiber optic sensors can also be used in many different applications. Fiber optic sensors are available in several types; among them, the Bragg grating sensor is being studied in this research. … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 6,497 accessesView PDFCite
