Behavior of Opening Concrete Frame Corners Reinforced with FRP

Discontinuity areas in concrete structures can be critical elements whose load-bearing capacity and behaviour can be decisive for the entire structure. This presented experimental research focuses therefore on verifying of the behaviour of subtle frame corners/​joints reinforced with glass-fibre composite reinforcement (GFRP). The main aim was to compare the behaviour of this part of the structure reinforced with composite and classical reinforcement when subjected to the positive bending moment (opening frame corners). The research builds on the knowledge gained from previous projects which were focused on the design of concrete structures reinforced with internal non-metallic reinforcement with regard to not only short-term [1], but also long-term behaviour [2].
