Research ArticleOpen accessIn the abstractHomogenization of Earthquake Catalogue in Terms of Magnitude in Iran and Adjoining RegionNoushin Naraghiaraghi, Mohd Nawawi, Syed Mustafizur Rahman et al.In any seismic hazard assessment a uniform earthquake catalogue is an essential parameter. In this research, an earthquake catalogue of Iran and adjacent areas was studied, using national and international catalogues. The considered region covers a quadrangle limited by 23 to 42°N and 42 to 65°E including Iran and adjacent areas. Earthquake data from the third millennium BC until 2014 … …Current Research in Geoscience, Vol. 6, Issue 1 · 11 Apr 2016 · 13,009 accessesView PDF Cite

Research ArticleOpen accessIn the abstractShort Period Spectral Acceleration Zonation of Tehran a Comparison between Slip and Activity Rates Data’sHadi Jarahi, Noushin Naraghiaraghi, Malihe NadalianThis study presents seismic hazard analysis and provides spectral iso acceleration maps based on slip rate (SR) and also activity rate (AR) of the faults. Nowadays modern seismic design of structures is complicated so special attention to the nature of the seismicity in active seismic zones like Tehran is required. Many studies, based on seismic hazard analysis have been done … …Current Research in Geoscience, Vol. 6, Issue 1 · 18 Feb 2016 · 8,264 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluation of Liquefaction Return Period for Bangalore Based on Standard Penetration Test Data: Performance Based ApproachK. S. Vipin, T. G. SitharamProblem statement: The conventional liquefaction evaluation is based on a deterministic approach. However in this method the uncertainty in the earthquake loading is not properly taken into account. However recent research in this field indicates that this uncertainty in the earthquake loading has to be considered in the liquefaction potential evaluation. Moreover the evaluation of liquefaction return period is not … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 3 · 30 Sep 2009 · 7,741 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAssessment of Weathering Layer Characteristics over OPL-135 in the Western Part of the Niger Delta Basin, South-South, NigeriaOkechukwu Frank Adizua, Adekunle Oyemade Sofolabo, Olomu Ivory Obi-EgbediAn up-hole seismic refraction survey was carried out in OPL-135 in the Western part of the Niger Delta Basin, (SS) Nigeria. A total of thirty seven (37) up-hole locations in a (4.0×3.750) km grid configuration were drilled and logged over the prospect. The focal objective for the study was to assess the weathering layer characteristics over the prospect, specifically, to … …Current Research in Geoscience, Vol. 11, Issue 1 · 3 Feb 2021 · 11,449 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSimilitude Distortion Compensation for a Small Scale Model of a Knee Braced Steel FrameNouredine Bourahla, Anthony BlakeboroughThe purpose of producing scaled physical models is to allow the assessment in the laboratory of the probable response of a structure to a prescribed loading. It is obviously of paramount importance to construct these models to reflect reality as accurately as possible. The problem encountered particularly for dynamic testing is that the similitude requirements are sometimes impractical. This paper … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 7 Aug 2015 · 7,176 accessesView PDF Cite
