Research ArticleOpen accessIn the author namesDefect Classification of Reinforced Concrete Structures with Nondestructive Tests Using Statistical and Machine Learning MethodsSajjad Sayyar-Roudsari, Armaghan Shalbaftabar, Farshid Damirchilo et al.In this study, twelve reinforced concrete beams were constructed, each with specified dimensions and initial compressive strength. The beams were divided into four groups: A control group without any defect, a void group featuring a centrally located void, a corrosion group and a debonding group. The impact echo test was used for nondestructive testing, gathering data on compressive and shear … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 11 Jun 2024 · 5,258 accessesView PDF Cite

Research ArticleOpen accessIn the author namesInvestigation 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 PDF Cite

Research ArticleOpen accessIn the author namesEvaluation of Fire Effects on Reinforced Concrete Columns Using Finite Element MethodSajjad Sayyar Roudsari, Taher M. Abu-LebdehIn this paper, four different Reinforced Concrete (RC) columns are analyzed with Finite Element (FE) ABAQUS software and validated experimentally. One of the RC columns, the control specimen, is subjected to only compressive force applied at both ends of the column, while the other three models were loaded under both compressive force and fire load. The temperature is applied to … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 20 Jun 2019 · 7,599 accessesView PDF Cite

Research ArticleOpen accessIn the author namesModeling of Reinforced Concrete Frames with Infill Walls Under Cyclic Loading Strengthening with CFRPMojtaba Fallahi, Sajjad Sayyar Roudsari, Mona Haghighifar, Rahmat MadandoostNowadays, using infill isolators in Reinforced Concrete (RC) structures is very common. In earlier research this infill isolators are usually considered as non-structural elements, but in recent researches it was demonstrated that infill has considerable effects on natural period, stiffness, strength and overall behavior of structure specially when it is subjected to seismic ground motions. In this study a one-bay … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 3 · 6 Jul 2018 · 8,444 accessesView PDF Cite
