Research ArticleOpen accessPhrase in the titleSeismic Assessment of Non-Seismically Designed Reinforced Concrete Frames with Core WallsTaek-Hyun Lee, Ki-Bong Choi, Taher Abu-LebdehThis study examines the seismic performance of four non-seismically designed reinforced concrete structures with core walls and proposes proper rehabilitation methods. The structures were selected based on the height of the structures, occupancy levels and floor plans. The seismic assessment results were compared based on the performance of the structures before rehabilitation and after rehabilitation. The results indicate that most … …American Journal of Applied Sciences, Vol. 11, Issue 11 · 13 Dec 2014 · 6,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractEquivalent Torsional-Warping Stiffness of Cores with Thin-Walled Open Cross-Section Using the Vlasov Torsion TheoryTriantafyllos Konstantinos MakariosIn order to calculate the equivalent torsional-warping stiffness of the Reinforced Concrete (RC) cores that have thin-walled open cross-section, a new analytical methodology, which combines the Vlasov torsion theory with the Bernoulli bending theory, is presented herein. As the basis of the calculations, we use the principal elastic reference system of the core from this we consider that is known. … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 2 · 23 May 2023 · 6,401 accessesView PDFCite
Research ArticleOpen accessIn the abstractDecision Making and Predicting the Cost for the Optimal Structural System of Multi-Story BuildingsHosam Elhegazy, Ahmed Ebid, Ibrahim M. Mahdi et al.There are numerous structural lateral systems used in multi-story buildings design such as the shear wall, frame system, framed with core, dual systems and superframes, etc. Additionally, the system of slabs such as (Solid Slab, Flat Slab, Flat plates, Hollow blocks, ... and Waffle Slabs). Generally, the structural systems of multi-story buildings are considered to be different types. Multi-story buildings … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 7 Sep 2021 · 6,289 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling, Simulation and Optimization of Steel Sandwich Panels under Blast LoadingSayed M. Soleimani, Nader H. Ghareeb, Nourhan H. ShakerHoneycomb sandwich panels are commonly preferred in structural engineering as a design element meant to protect against blast loading, and this owes primarily to the fact that they are light in weight (due to the voids present) whilst carrying high energy absorption capacities. A widespread surge in acts of terrorism, and the resultant threat posed to structures, presents structural engineers … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 3 · 24 Aug 2018 · 7,858 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlattening Effect on Heat Transfer Characteristics of a Sintered-Wick Heat PipeWeeranut Intagun, Pradit Terdtoon, Phurt SakulchangsatjataiThe effect of pipe flattening on heat transfer characteristics and the internal phenomena of a sintered-wick heat pipe has been investigated by using three-dimensional Finite Element Method. The calculation domains were focused at three important regions, i.e., vapor core, wick and wall. The Cartesian coordinates and the three-dimensional tetrahedral elements were applied in this model. The selected total elements were … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 4 Jul 2013 · 7,342 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign, Development and Numerical Analysis of Honeycomb Core with Variable Crushing StrengthShabnam Sadeghi Esfahlani, Hassan Shirvani, Ayoub Shirvani et al.A honeycomb core with half-circular cut-away sections at the spine (the adjoining cell walls) is designed and developed and numerically tested under axial dynamic load condition. The parametric study is invoked to identify the effect of various circular cut-away dimensions. In one embodiment a half-circular shaped cuts are removed from the top of the cell where the cell is impacted … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 15 Jan 2013 · 7,572 accessesView PDFCite
Research ArticleOpen accessIn the abstractRepairing and Strengthening of an Existing Reinforced Concrete Building: A North Cyprus PerspectiveHakan Yalciner, Amir A. HedayatProblem statement: Inadequate attention during design and construction of some of Reinforced Concrete (RC) buildings in North Cyprus has raised questions about the performance level of these existing buildings under future earthquakes. Approach: Column jacketing, adding steel braces and new shear walls to an existing building are common strengthening methods used by practical engineers in North Cyprus to increase the … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 9,787 accessesView PDFCite
