Research ArticleOpen accessEvery word in the titleEffect of Corrosion Damage on the Ductility Performance of Concrete ColumnsJ. Revathy, K. Suguna, Juan Eduardo Suarez RivadeneiraProblem statement: An experimental investigation was carried out on reinforced concrete columns with corroding reinforcement to assess the residual strength and ductility performance of columns. Approach: An accelerated corrosion regime of different degrees of corrosion damage of 10 and 25% were induced in the steel reinforcement of concrete columns. The columns were then tested under uni-axial compression until failure. Results: … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,888 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDuctility Performance of Hybrid Fibre Reinforced ConcreteS. Eswari, P.N. Raghunath, K. SugunaThis study presents a study on the ductility performance of hybrid fibre reinforced concrete. The influence of fibre content on the ductility performance of hybrid fibre reinforced concrete specimens having different fibre volume fractions was investigated. The parameters of investigation included modulus of rupture, ultimate load, service load, ultimate and service load deflection, crack width, energy ductility and deflection ductility. … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,290 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSeismic Performance Evaluation of Reinforced Concrete Moment Resisting Frames with Various Ductility in Low Seismic ZoneN. Choopool, V. BoonyapinyoProblem statement: Bangkok, the capital of Thailand, is at moderate risk for distant earthquake due to the ability of soft soil to amplify ground motion about 3-4 times although it locates in low seismic zone. In addition, before the enforcement of seismic loading for buildings in the Ministerial Law in 2007, many existing reinforced concrete buildings in Bangkok may have … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 27 Jan 2011 · 9,493 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStrength and Ductility of Randomly Distributed Palm Fibers Reinforced Silty-Sand SoilsS.M. Marandi, M.H. Bagheripour, R. Rahgozar, H. ZareThis paper investigates the resultant strength and ductility behavior when randomly distributed palm fibers are used to reinforce silty-sand soils. The composite soils were tested under laboratory conditions and examined for unconfined compression strength (UCS), California Bearing Ratio (CBR) and compaction test. The results indicated that; the maximum and residual strengths, orientation of surface failures, ductility and the stress-strain relationship … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 8,857 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInvestigation of Sandwich Panel Under High Temperature Loading Using Finite Element AnalysisSajjad Sayyar Roudsari, Armaghan Shalbaftabar, Taher M. Abu-Lebdeh et al.Structural and nonstructural members are always encountered with extreme loading conditions. In case of nonstructural members, the failure happens much sooner due to lack of load capacity. The nonstructural elements are not designed for structural loading conditions. However, they might be impacted to other loading types such as fire. In recent years, the use of 3D panel is one of … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 1 Jul 2020 · 7,678 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Effects of Using Crumb Rubber Modified Binder in an Asphalt PavementSayed Mohamad Soleimani, Alanoud Faheiman, Zainab MowazeIn this study, laboratory investigations have been carried out to characterize and demonstrate the improved performance of asphalt after modifying it with crumb rubber. The study has been divided into two main parts. Firstly, the physical characterizations of crumb rubber modified bitumen with different percentages of crumb rubber have been evaluated using penetration, softening point, viscosity, ductility and thin film … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 14 May 2020 · 8,377 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMulti-Objective Optimization of FRP Jackets for Improving the Seismic Response of Reinforced Concrete FramesCorrado Chisari, Chiara BedonIn this study, a multi-objective Genetic Algorithm (GA) optimization procedure is proposed for the seismic retrofitting of Reinforced Concrete (RC) building frames via Fiber-Reinforced Polymer (FRP) jackets. The optimization problem is solved via numerically efficient but accurate Finite-Element (FE) models able to take into account the strengthening and ductility increase contribution for a given FRP jacketing configuration. Based on a … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 27 Sep 2016 · 8,825 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Effect of Using Hysteresis Models (Bilinear and Modified Clough) on Seismic Demands of Single Degree of Freedom SystemsAhmad N. Tarawneh, Sereen A. Majdalaweyh, Bassam Z. MahasnehBased on nonlinear inelastic dynamic analysis of Single Degree Of Freedom systems (SDOF), this work investigates the effect of different parameters on the seismic response of these systems. Generalized SDOF systems that present both short and long period structures are subjected to two sets of synthetic ground motions according to the site condition; stiff rock site and stiff soil one, … …American Journal of Applied Sciences, Vol. 13, Issue 8 · 17 Aug 2016 · 7,729 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExperimental 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 PDFCite
