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 PDF Cite

Research ArticleOpen accessIn the abstractUncertainty Assessment for the Buckling Analysis of Glass Columns with Random ParametersMohammad Momeni, Chiara BedonLoad-bearing elements composed of glass, as known, are often susceptible to buckling collapse mechanisms. This intrinsic characteristic (and thus potential limitation for design) typically derives from the use of relatively small thicknesses to cover large spans and surfaces, thus resulting in a multitude of columns, beams, or plates that are characterized by high slenderness. In the literature, accordingly, several and … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 22 Dec 2020 · 6,295 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNonlinear Analysis of RC Box Culverts Resting on a Linear Elastic SoilDaniele Baraldi, Fabio Minghini, Enrico Tezzon, Nerio TulliniIn the analyses presented, the soil-structure interaction is accounted for by means of a FE-BIE approach, in which the structure is modelled with displacement-based beam finite elements, whereas the boundary between structure and substrate is described in terms of surface tractions by means of a boundary integral equation incorporating a suitable Green's function. This mixed formulation ensures full continuity between … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 8 Feb 2018 · 12,632 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Adaptive Procedure for the Limit Analysis of FRP Reinforced Masonry Vaults and ApplicationsAndrea Chiozzi, Gabriele Milani, Nicola Grillanda, Antonio TralliThe present paper discusses an adaptive procedure for the kinematic limit analysis of FRP reinforced masonry vaults through applications. The approach relies on a new Genetic Algorithm NURBS-based general framework, which has been recently presented by the authors. The basic idea consists into exploiting the NURBS structure of a CAD geometric 3D model of the selected reinforced masonry vault, in … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 5 Oct 2016 · 8,522 accessesView PDF Cite
