Abstract

This paper presents the results of the research on a five-span prestressed concrete road bridge under static load performed at different stages of its repair. All bridge spans become reinforced by CFRP strips glued on bottom flanges of main girders, and external flat steel stirrups, as well as overlaid a new concrete deck layer. The main aim of the conducted bridge repair was to increase its load capacity to 300 kn (class C) according to the polish loads standard (PN-85/S-10030). The results obtained during the research at different stages of repairs were conducive to determining the behavior of the analyzed span structure under static loads, which allowed for an assessment of the efficiency of the strengthening, as well as establishment of guidelines for future reference concerning this type of strengthening in the engineering practice.
