Research ArticleOpen accessIn the abstractThe Multiple Tuned Mass Damper for Passive Control of Structures by Cuckoo AlgorithmHamid Jafari Nia, Amir Hossein Heidari, Hamid Reza Babaali, Kaveh Ostad-Ali-AskariAdjustable mass dampers are recently used to reduce seismic vibrations of engineering structures. Function of these types of systems requires a suitable setting of their parameters. In this study, a practical method to design Multiple Tuned Mass Dampers (MTMD) has been proposed to minimize the maximum displacement of roof, acceleration of roof and TMDs displacement to reduce the seismic response … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 16 Jul 2020 · 7,392 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Contribution of the CDP Gathers and Pre-Stack Seismic Inversion in the Prospect Evaluation: A Case Study of El Mansoura Field, Nile Delta, EgyptMohamed Hussein, Ahmed Abu El-Ata, Mohamed El-BehiryThis case study showing the usefulness of the Common Depth Point (CDP’s) analysis to assess the amplitude response which is similar at two cases (gas-bearing and dry sands) after stack, using the Amplitude Versus Offset (AVO) analysis and the pre-stack inversion to understand the reservoir configuration and its relationship to the different amplitude response. The results led to a high … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 24 Jul 2019 · 7,794 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIn-Plane Behavior of Infills using Glass Fiber Shear Connectors in Textile Reinforced Mortar (TRM) TechniqueFarhad Akhoundi, Graça Vasconcelos, Paulo LourençoMasonry has a widespread use in the construction of the buildings even in reinforced concrete or steel frames. Past earthquakes have demonstrated the vulnerability of masonry infills resulted in the human life losses and economic costs. Recently innovative strengthening techniques such as Textile Reinforced Mortar technique (TRM) is used for enhancing the seismic response of the infills. Different procedures were … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 14 Jan 2018 · 9,087 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExperimental Evaluation of the Raking Energy in Damping System of Steel Stud Partition WallsSalah Amer, Sameer Hamoush, Taher M. Abu-LebdehNonstructural partition walls are usually specified based on the best practice without any structural design calculations. However, given the likely severe earthquake damage to nonstructural components and the substantial cost of repair to such components, it is imperative that we develop an understanding of the seismic response of the nonstructural partition walls when subjected to earthquake loading conditions. The main … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 6 Nov 2015 · 7,640 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHigh Rate-Dependent Interaction Diagrams for Reinforced Concrete ColumnsTaher Abu-Lebdeh, Sameer Hamoush, Wonchang Choi, Moayyad Al NasraProblem statement: There is a need to better understand the rate dependence behavior of reinforced concrete structures in order to improve their response to impact and blast loads. Analysis and design of reinforced concrete structures subjected to seismic loadings has been recommended in many FEMA guidelines. However, reevaluation of design becomes extremely important in cases where large deformations are expected … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 27 Jan 2011 · 8,020 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNonlinear Behavior of Single Piles in Jacket Type Offshore Platforms Using Incremental Dynamic AnalysisMohammad Amin Assareh, Behrouz AsgarianThe operation for offshore oil has become an important issue in the recent years. Offshore platforms are some of those structures which are built to withstand environmental and accidental loads during oil exploitation operation. One of the most usual types of these platforms is the Jacket Type Offshore Platform (JTOP) which can be divided into three important parts, which are … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 9,299 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

Research ArticleOpen accessAll words, across the recordOptimal Arrangement of Energy-Dissipating Members for Seismic Retrofitting of Truss StructuresToru Takeuchi, Yusuke Kinouchi, Ryota Matsui, Toshiyuki OgawaAlthough passive response control design is a popular method, an arrangement methodology for energy-dissipating devices in spatial structures has not been established yet. In this study, optimization techniques are applied to arrangements of energy-dissipating devices in truss tower structures. First, a response prediction rule using the response spectrum and the equivalent linearization method is proposed. Then, a genetic algorithm is … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 14 Jul 2015 · 7,619 accessesView PDF Cite
