Modeling of Mechanical Interaction of Reinforcement with Matrix Composite

Abstract

There is solved the problem on determination influence of contact parameters between composite reinforcement and a matrix on strengthening and stiffness of a supporting structure. It is executed on a finite element modelling basis. There is determined influence a constant of friction between rebars and concrete on slip between them and a formed gap at loading. Also it is analysed rebars location influence on the beam stress-strain condition.
