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 tapes glued on bottom flanges of main beams, 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.
