Abstract:

This paper presented the method, scope, results and their analysis of the research and the main conclusions drawn from static field load tests performed on a five-span prestressed concrete road bridge after its repair. The bridge with the effective spans of 18.00 m is located over the Nysa Klodzka River in Paczkow (Poland). All bridge span beams became reinforced by CFRP tapes glued on bottom flanges of main beams 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 of the bridge after its repair at field load tests 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 maintenance in the engineering practice.
