RESEARCH OF ROAD BRIDGE BEAMS STRENGTHENED BY CFRP TAPES IN THE DIFFERENT REPAIR PHASES

Article Summary   by:toffi_75     Original Authors: Arkadiusz MORDAK; Zbigniew MAŃKO

The paper is presented the results of experimental research conducted on the post-tensioned pre-stressed concrete road bridge under statical loads made on different phases of executing of its repair. Bridge spans were strengthened by gluing CFRP stripes on bottom flanges of main beams and installing on beams of external stirrups executed from steel flat bars. Main purpose of the bridge repair was to increasing the load capacity of object to C class of loads (300 kN) according to the Polish Standards (PN-85/S-10030). On the base of obtained results from research and calculation by FEM the behaviour of tested span structures was evaluated at the different phases of repair, what it was permitted an effectiveness of maintenance and elaborate guidelines for using of this type of reinforced manner in the future in engineering practice.
