Research ArticleOpen accessEvery word in the titleBamboo Lightweight Shear Walls: Modeling and Identification of Sheathing-to-Framing Connections for Seismic Response AnalysisGiorgia Di Gangi, Cristoforo Demartino, Giuseppe QuarantaThe need for enhancing the sustainability of civil constructions has originated an increasing interest in the use of engineered bamboo-based products within the building sector. Nonetheless, while the static response of bamboo-made structures has been largely investigated, experimental and numerical researches concerning the response under dynamic loads are limited. Therefore, the present work deals with the assessment of the seismic … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 16 Jun 2020 · 6,943 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSeismic Fragility Assessment of RC Frame Equipped by Visco-Elastic Dampers Using NLTHA and FNAAli A. Rostam Alilou, Majid PouraminianIn recent years, the issue of lower computational cost and analysis time has been the important factors for the structural analysts. In the meantime, after years of its introduction as an analysis having features of nonlinear analysis, the Fast Nonlinear Analysis (FNA) claims to have a higher performance speed than other nonlinear analyses, but has been less used by the … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 18 Jul 2019 · 8,413 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCyclic Instability of Shape-Memory Alloys in Seismic Isolation SystemsFilipe Amarante dos Santos, Corneliu Cismasiu, Francisco Braz FernandesShape-memory alloys are being progressively introduced as kernel components in seismic retrofitting devices for civil engineering structures. In order to control the instability associated with the first mechanical cycles, a training procedure is usually implemented, which stabilizes the superelastic behavior of the alloy. This paper addresses the characterization of the cyclic behavior of an austenitic NiTi alloy with emphasis on … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 7 Jan 2018 · 6,854 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleContinuous Wavelet Transform Based Spectral Decomposition of 3d Seismic Data for Reservoir Characterization in Oyi Field, se Niger DeltaChukwuemeka Ngozi Ehirim, Andifon Sylvester AkpanContinuous Wavelet Transform (CWT) is one of the most used wavelet transform based spectral decomposition methods in the direct detection of hydrocarbons and as an indicator of stratigraphic variability due to its optimal time-frequency resolution and variable time window requirements. CWT based spectral decomposition was applied on a 3D Post Stack Time Migrated (PSTM) seismic data acquired over a producing … …American Journal of Applied Sciences, Vol. 14, Issue 8 · 28 Apr 2017 · 7,791 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSeismic Design of Masonry and Reinforced Concrete Infilled Frames: A Comprehensive OverviewMarina L. MorettiDespite the extensive research on the seismic behavior of infilled frames since 1960’s, there is no general consensus towards a unified approach. Purpose of this study is to review the existing analytical and experimental research, as well as code provisions, on masonry and on reinforced concrete infilled frames. The basic characteristics of infilled frames and how these affect seismic performance … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 30 Nov 2015 · 8,047 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvestigation of the Behavior of Tailings Earthen Dam Under Seismic ConditionsDebarghya Chakraborty, Deepankar ChoudhuryProblem statement: A number of tailings earthen dams have failed during past earthquakes. The failure of tailings dam ultimately results into the release of the stored tailings waste deposit in the surrounding locality. To reduce such damage of tailings earthen dam, a detail method of seismic analysis is very much essential which can be used reliably for the design and … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 3 · 30 Sep 2009 · 8,559 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSeismic 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 accessEvery word in the titleExperimental Investigation on Three Dimensional RC Infilled Frame - RC Plane Frame Interactions With Slab for Seismic ResistanceSuyamburaja Arulselvan, K. SubramanianExperimental investigation was planned and conducted to study the influence of brick masonry infill and slab in a three-dimensional reinforced cement concrete frame. In this study, one-fifth scale 3D R.C frame representing single story, three bays with central bay brick infill at the sides and a long single bay without infill in the middle of the frame along loading direction … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,313 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimal 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 PDFCite
Research ArticleOpen accessEvery word in the titleSeismic 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
