Composite reinforcement is a good alternative metal reinforcement for its high tensile strength, dielectric properties, and high corrosion resistance, but the range of its application is limited due to its low modulus of deformation and adhesion to concrete. The main objective is to develop and analyze the numerical model of composite reinforcement with concrete interaction, to allow further modeling work plastikconcrete(polimercomposite) construction of transport facilities.In research, the authors conducted a series of experiments pulling with "sand" fiberglass rod from the bottom (Pull-out test) in accordance with GOST 31938-2012, who helped evaluate the limit of adhesion fiberglass reinforcement with concrete. According to the results plotted the "pull out force -slip reinforcement relatively concrete", the investigation analyzed a variety of existing models clutch metal reinforcement, but to approximate this dependence proposed piecewise linear function, which is used for the further implementation of the numerical model based on linear relationships with the ultimate rigidity. The results of numerical experiments performed on this model are in good agreement with the experimental data with enough input linear relations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
