Research ArticleOpen accessIn the abstractSeismic Response Evaluation of Moment Resistant Frame with Built-Up Column SectionMohammad Ebrahimi, Hesam Sharifian, Mohammad AhangarProblem statement: Moment Resisting Frame (MRF) is widely used as lateral resisting systems when sufficient ductility and deformability are to be met. Response of these structures is strictly dependent upon behavior of their joints, whereas the analysis of steel moment resisting frames generally has been performed without considering the accurate connection behavior. Approach: In this study Finite Element (FE) models … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,279 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison the Proposed Probabilistic-Based Time-History and the Traditional PSHA ApproachA. NicknamThe main objective of this article is to demonstrate the ability of our technique in estimating the probabilistic-based time-history to be used in dynamic analysis of structures. The result of using our technique is compared with that of traditional approach proposed by Cornell (Cornell, 1968), in the form of response spectrum through a case study. Good agreement of the two … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 6,945 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modeling for Shakedown Analysis of Offshore StructuresMohammad Javad Fadaee, Hamed Saffari, Ramin TabatabaeiThe shakedown analysis process of an offshore structure having elastic-plastic material presented. The finite element model of the structure has been developed first, and then a simple method has been applied for shakedown analysis using matrix tool. Simplifying the relationships together with applying the theory concepts of shakedown analysis is one of the characteristics of the presented method for practical … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,065 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impact of Foreign Ownership on Firm Performance, Evidence from an Emerging Market: TurkeyAli Osman Gurbuz, Asli AybarsProblem statement: The inflows of foreign direct investment are important sources of finance for developing countries. Due to the increase in the amount of the international flows of capital over the last three decades, the issue of the possible impact of foreign direct investment on the performance of corporations and thus the economy has gained increased attention. The purpose of … …American Journal of Economics and Business Administration, Vol. 2, Issue 4 · 28 Nov 2010 · 15,819 accessesView PDFCite
Research ArticleOpen accessIn the abstractReliability 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 accessIn the abstractEvolution of Spatial Correlation of Mean Diameter: A Case Study of Trees in Natural Dipterocarp ForestRafida M. Elobaid, Mahendran Shitan, Noor Akma Ibrahim et al.Problem statement: Spatial modeling has many applications in various fields like agriculture, meteorology, forestry and it takes into consideration the spatial correlation structures. In the field of forestry the growth rate, in particular, the diameter of trees is usually an important parameter. The growth rate of trees in a forest is likely to be influenced by various factors like nutrients, … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,536 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Study of Morphological Structure, Phase Structure and Molecular Structure of Collagen-PEO 600K Blends for Tissue Engineering ApplicationN. F. Mohd Nasir, M. G. Raha, N. A. Kadri et al.A new material which is collagen/ poly (ethylene oxide) (PEO) blend was developed to determine its possibility as a promising material for tissue scaffold. PEO with average molecular weight of 600,000 and collagen originated from calf skin were dispersed in 0.1 M acetic acid to prepare a concentration of 1 wt% for PEO and 0.15 wt% for collagen. The collagen-PEO600K … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 7,422 accessesView PDFCite
Research ArticleOpen accessIn the abstractFailure Diagnosis on Discrete Event SystemsSihem Kechida, Nasr Eddine DebbacheThe modern technology advances to a point where it is possible and extensively desirable to improve reliability and the technical process safety. This is achieved by computer implanted FDI procedures (Fault Detection and Isolation). However, the malfunction of actuators, sensors and of the process components, as well as erroneous actions of human operators can have some disastrous consequences in high … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,888 accessesView PDFCite
InvestigationOpen accessAll words, across the recordInvestigating the Parameters Influencing the Behavior of Knee Braced Steel StructuresEdris Farokhi, Mehrdad GordiniIn Knee-Braced Frames (KBF), the brace is connected to the knee element rather than the beam-column joint. For reasons such as having sufficient lateral stiffness despite its adequate ductile behavior, the concentration of damage in the Double Knee-Braced structural elements and also ease of repair and replacement of these elements after an earthquake, this bracing system is preferred over conventional … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 21 Sep 2015 · 7,808 accessesView PDFCite
