Abstract:
The paper presents the results of research aiming at exposing the possibility and practical advantages resulting from the application of stressed composite strip (Carbon Fibre Reinforced Polymer) to strengthen concrete structures. The distribution of shear stress in the glue joint was determined on the basis of theoretical analysis of equilibrium state. This knowledge allowed the system of stressing CFRP strip and strengthening the prestressed girder to be designed. The girder was tested under static and dynamic loads. The paper presents the results of tests and conclusions based on them.
