The article presents the analysis of FRP composite materials strengthening systems for pre-stressed bridge structure elements. Displacements and strains of main beams of bridges were investigated before and after the strengthening executed by FRP composite materials. Test load field and theoretical analysis were performed after bridge structure repair. The results of bridge structures after strengthening in field load tests allowed for an assessment of the efficiency of the strengthening, as well as establishment of guidelines for future reference concerning this type of maintenance in the engineering practice.
