Research ArticleOpen accessIn the keywordsA Numerical Treatment of Air Flow Model in the Area Under the Station Platform of Thailand BTS Sky TrainNopparat PochaiProblem statement: The area under Phayathai station platform of sky train in Bangkok, Thailand, has a problem of air pollution control. Approach:The Bangkok Mass Transit System Company tries to set up the electric fans inside the area for air flow improvement. Results: The flow of the air is still not smooth and the air quality is still lower than standard. … …American Journal of Applied Sciences, Vol. 7, Issue 11 · 8 Nov 2010 · 7,096 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHow Does The Bone Shaft Geometry Affect its Bending Properties?Kaveh PourAkbar Saffar, Nima JamilPour, Seyed Mohammad RajaaiIn this research, ten fresh specimens of sheep tibiae were provided from slaughtered animals. Whole bone specimens were loaded in three-point bending according to standard wet bone test protocols. Mechanical properties were determined and compared with the results which were obtained from two dry bone tests. The results showed that fracture bending moment and bone extrinsic stiffness had significant relations … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 8,154 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFinite 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 · 7,445 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDynamic Solution Code for Structural Analysis upon Joint ElementS. A. Sadrnejad, M. LabibzadehThe analysis of large structures mostly requires a complete three dimensional finite element discretization. Stability of such structures includes not only the stability of structure itself but also that of foundation as well as interconnection elements. The general instability of a structure may be affected by two aspects, firstly, an inappropriate preliminary classical design of the structure and inadequate control … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,446 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLow Cycle Fatigue Behavior of a Reduced End Plate Moment Connection (T-Stub)Chemin Lim, Wonchang Choi, Emmett A. Sumner, Taher Abu-LebdehProblem statement: In this research, four reduced End Plate Moment Connection (EPMC) specimens (T-stubs) are tested to verify the numerical and theoretical methods for preanalysis of the Low Cycle Fatigue (LCF) behavior of a four-bolt extended unstiffened EPMC. Approach: The T-stub specimens are bolted to a support frame and a monotonic load is applied to the stem plate. Yield line … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 12 Jan 2012 · 7,402 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA 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 · 8,292 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPreliminary Experimental and Finite-Element Numerical Assessment of the Structural Performance of SMA-Reinforced GFRP SystemsFilipe Amarante dos Santos, Chiara BedonIn this study, the feasibility and potentiality of a novel design concept is explored by means of small scale experimental tests and Finite-Element numerical simulation. Taking advantage of the intrinsic potentiality of Shape-Memory Alloys wires able to work as adaptive actuators when subjected to joule heating, a 'smart-GFRP' concept consisting in Glass-Fiber-Reinforced-Polymer (GFRP) structural members with a SMA reinforcement is … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 27 Sep 2016 · 8,298 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFinite Element Study of the Stress Response of Bi-Directional Corrugated-Strip Core Sandwich BeamSuphattharachai Chomphan, Manit LeekitwattanaProblem statement: In engineering design, stress affects the size of structural member. A suitable topology of structure should be designed to optimize the stress. Approach: This study presents an alternative topology of truss-like core sandwich beam referred to here as bi-directional corrugated-strip core topology. A finite element method is used to study the stress response of three point loaded truss-like … …Journal of Computer Science, Vol. 7, Issue 9 · 23 Jul 2011 · 7,064 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSeismic Behavior of Vertical Shear Links made of Easy-Going SteelAmir Saedi Daryan, Hesam Bahrampoor, Masood Ziaei et al.Problem Statement: Since the time that steel was first used as a construction material, engineers have attempted to increase strength, reduce weight and produce more economical structures by using elegant member sections. However, the increase in steel strength and the decrease in cross section area are not always useful and in some cases it is necessary to reduce the strength … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,218 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDetermination of Flux linkage Characteristics and Inductance of a Submersible Switched Reluctance Motor using Software ToolsSundaram Maruthachalam, Navaneethan PalaniswamyProblem statement: The Switched Reluctance Motor (SRM) is an old member of the Electric Machines Family. It’s simple structure, ruggedness and inexpensive manufacturing capability make it more attractive for Industrial applications. Now, the applications of switched reluctance motors in various industrial fields are tried by many engineers. However, switched reluctance motors are not used so far in submersible underwater motor … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,585 accessesView PDFCite
