Design guides

GFRP rebars are designed for reinforcement of prestressed and non-prestressed construction structures and components (foundations of buildings and structures, reinforcement of concrete floors, reinforcement of roads, etc.). Recently FRP rebars have been used as an alternative to steel rebars for reinforcement of concrete structures. However in some cases, steel rebars cannot be directly substituted with their FRP analogues, due to differences in their mechanical properties. That is why applicable guidelines shall be followed during design of FRP-reinforced concrete structures. The most crucial differences, like lower modulus of elasticity and shear strength, limited maximum sustained shear stress of FRP rebars, shall be also considered before design.
