Fiber Reinforced Polymers (FRP) are commonly used nowadays for strengthening deteriorated structures. The purpose of this research was to determine the combined behavior of masonry walls and reinforcing meshes together, according to their deformation characteristics. A sample wall with average masonry parameters and seven different common polymer nets on them were modeled in Abaqus Software. Moreover, a case study wall was also modeled according to the strength values obtained from direct testing of a demolished masonry wall that was shaped as secondary blocks for reusing purposes. In addition to the analysis of this plain recovered wall, the strengthened version of it with carbon fiber polymer mesh was also modeled. The results obtained from the theoretical sample wall and the case study wall with plain and reinforced alternatives stated that; the compatibility of deformation characteristics between the wall and the reinforcing mesh is the key for combined strength behavior of the wall. Lastly, besides illustrating and discussing all the stress-strain conditions for the analyzed cases, this study also offered a formula for the detection of combined behavior in question, according to the material properties of unreinforced wall and reinforcing mesh separately. This formula is quite useful in order to decide to the suitable mesh type prior to the application.

Seismic strengthening of a mid-rise reinforced concrete frame using CFRPs: an application from real life Tan, Mustafa Tümer; Özcebe, Güney; Department of Civil Engineering (2009) FRP retrofitting allows the utilization of brick infill walls as lateral load resisting elements. This practical retrofit scheme is a strong alternative to strengthen low to mid-rise deficient reinforced concrete (RC) structures in Turkey. The advantages of the FRP applications, to name a few, are the speed of construction and elimination of the need for building evacuation during construction. In this retrofit scheme, infill walls are adopted to the existing frame system by using FRP tension ties anchored ...
Nonlinear behaviour and stress concentrations in natural fiber composites under transverse loading Çakmakçı, Onur; Kadıoğlu, Fevzi Suat; Sabuncuoğlu, Barış; Department of Mechanical Engineering (2019) Natural fiber reinforced polymer composite materials attracted attention of the researchers recently. Some of them, especially flax fiber composites, do have quite favorable mechanical properties compared to synthetic fibers like E-glass. In this study, micromechanical model of flax fiber reinforced composite under transverse loading is investigated and compared with conventional synthetic fibers. The study includes variety of strains and response of the material under large deformations. Finite element mod...
Mechanical properties of hybrid fiber reinforced concrete Yurtseven, A. E.; Yaman, İsmail Özgür; Tokyay, Mustafa (2006-07-07) Fiber reinforcement is commonly used to provide toughness and ductility to brittle cementitious matrices. Reinforcement of concrete with a single type of fiber may improve the desired properties to a limited level. A composite can be termed as hybrid, if two or more types of fibers are rationally combined to produce a composite that derives benefits from each of the individual fibers and exhibits a synergetic response. This study aims to characterize and quantify the mechanical properties of hybrid fiber re...
Fiber/matrix interface stress analysis of flax-fiber composites under transverse loading considering material nonlinearity SABUNCUOĞLU, BARIŞ; Cakmakci, Onur; Kadıoğlu, Fevzi Suat (SAGE Publications, 2020-05-01) Distribution of stresses in fiber/matrix interface in UD flax fiber reinforced composites is investigated under transverse loading and compared with conventional synthetic fibers. Micro-scale finite element models with representative volume elements are generated with various fiber packing types and fiber volume ratios. The study is performed for various strain values, which take into account the material nonlinearity of matrix. The results show that significantly lower stress concentrations exist in the ca...
Analytical modeling of fiber reinforced composite deep beams Yağmur, Eren; Burak Bakır, Burcu; Department of Civil Engineering (2018) Discrete fibers are often used as reinforcement to increase the tensile and shear strengths of concrete. For many years, the behavior of fiber reinforced composite members has been investigated both experimentally and analytically. The influence of fibers on the behavior of shear critical members is quite significant, therefore, it is inevitable to develop a method, which estimates the shear strength of fiber reinforced composite deep beams realistically. This is why one of the main objectives of this study...
