Research ArticleOpen accessEvery word in the titleReliability-Based Earthquake Design of Jacket-Type Offshore Platforms Considering Pile-Soil-Structure InteractionBehrouz Asgarian, Hossein AgheshluiThere are plenty of uncertainties in environmental condition of ocean and also in platform element capacities. Reliability-based method could consider these uncertainties. A reliability-based earthquake design method was used to determine the earthquake LRFD parameters for two conventional, steel, pile-supported (template-type) offshore platforms located in the Persian Gulf. The pile-soil-structure interaction, the buckling and postbuckling behavior of the braces were … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,509 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePrevalence and Correlates of PTSD among High School Students After the Earthquake Disaster in the City of Bam, IranHassan Ziaaddini, Nouzar Nakhaee, Kolsoom BehzadiEarthquake and its consequences have become recognized as a growing health problem in recent years in developing countries. On 26 December, 2003 at 5.26 Am, the town of Bam in the south eastern part of Iran suffered an earthquake of 6.3 on the Richter scale, killing more than 26000 people. This study was aimed to investigate the prevalence of PTSD … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,962 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Earthquakes on Some Kind of BuildingsJ. Alberto Escobar S., J. Antonio Mendoza, Roberto Gómez M.A new method that simplifies the current static seismic torsion design procedure for buildings is proposed. Distribution of the shear forces among the storey-resistant elements designed by torsion and of the factors which affect the design eccentricity, specially accidental eccentricity, are studied. It is demonstrated that the effect of accidental eccentricity is always additive for the structural elements. There is … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 6,347 accessesView PDFCite
Review ArticleOpen accessIn the keywordsPSHA Study Using EZ-Frisk Software Case Study Baychebaq Dam SiteHadi JarahiAwareness of seismicity, is the earliest requirement in seismic design of Dam constructions. This article is devoted to study on Seismotectonic and seismicity and also seismic risk analysis of the Baychebaq reservoir dam. These studies involve detecting seismic sources and assessing seismicity parameters. According to the studies, Peak Ground Acceleration (PGA) is 0.1 gal. This PHA may be related to … …Current Research in Geoscience, Vol. 7, Issue 2 · 10 Nov 2017 · 7,802 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCultural Identity Expressions through Visual Analysis in Post-Disaster HousingAsal Kamani Fard, Mohd Hamdan Ahmad, Dilshan Remaz OssenProblem statement: The incidence of natural disasters as well as followed human beings’ efforts for reestablishing life is considered as unavoidable essence of nature. Whilst, the interdisciplinary theme of post disaster recovery and reconstruction has been researched worldwide in order to examine its different aspects. And within architectural interests, evaluating the housing reconstruction programs would lead to beneficial clues through … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,270 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 · 7,211 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDynamic Analysis of Structures Using Neural NetworksN. Ahmadi, R. Kamyab Moghadas, A. LavaeiIn the recent years, neural networks are considered as the best candidate for fast approximation with arbitrary accuracy in the time consuming problems. Dynamic analysis of structures against earthquake has the time consuming process. We employed two kinds of neural networks: Generalized Regression neural network (GR) and Back-Propagation Wavenet neural network (BPW), for approximating of dynamic time history response of … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,154 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLiquefaction Susceptibility in the Northern Provinces of ThailandSupot Teachavorasinskun, Pichai Pattararattanakul, Pulpong PongvithayapranuProblem statement: There are quite a few active faults recently found in the western and northern parts of Thailand, which could possibly induce earthquakes of magnitude (ML) of 5.5-6.5. Although seismic design code has been enforced in the area since 1980, the fundamental knowledge on dynamic soil behavior has not been extensively attained. Approach: Collection of existing borehole information in … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,331 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFinite Element Analysis of Large Capacity Endplate Steel ConnectionsMohamed Eldemerdash, Taher Abu-Lebdeh, Moayyad Al NasraProblem statement: Extended endplate connection is one of the most widely used beam-to column steel connections because of its fabrication simplicity, good overall performance and cost effectiveness compared with other connection types. The objective of this research is to develop three-dimensional finite element models to study the behavior of large capacity eight-bolt extended un-stiffened wide endplate steel connections, using current-technology … …Journal of Computer Science, Vol. 8, Issue 4 · 28 Jan 2012 · 6,912 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Viewpoint for Seismotectonic ZoningReza Derakhshani, Seyed Saeed EslamiProblem statement: Seismotectonic zoning has always been used to get access to intracontinental seismic deformation whereas zoning is not enough reliable in regard with small-scale studies. Approach: This research presents a theoretical model on the basis of plate tectonic theory to introduce a new approach to conduct zoning in terms of seismic deformation. Results: The result of this research not … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 7,663 accessesView PDFCite
