Abstract
The article presents a method for calculating the strength of concrete elements with non-metallic fiber, rod and external reinforcement. The algorithm and the calculation program are shown, which are based on the use of a nonlinear deformation model of the normal section of such elements, taking into account the real deformation properties of materials under static and short-term dynamic loading.
Highlights
Non-metallic materials for the reinforcement of concrete structures can be divided into 3 groups: fiber reinforcement to create fiber-reinforced concrete (FRC), composite reinforcement (FRP bars) for core reinforcement and external composite reinforcement (Externally Bonded FRP Systems - EBFS) for strengthening concrete structures
According to studies [1,2,3,4], it is the great differ in the deformation characteristics between of FRC, FRP and EBFS and traditional materials analogues
The existing design models describing the strength of sections of traditional reinforced concrete elements cannot be used to calculate concrete elements reinforced with new types of non-metallic reinforcement
Summary
Non-metallic materials for the reinforcement of concrete structures can be divided into 3 groups: fiber reinforcement (discrete fibers - DF) to create fiber-reinforced concrete (FRC), composite reinforcement (FRP bars) for core reinforcement and external composite reinforcement (Externally Bonded FRP Systems - EBFS) for strengthening concrete structures.
