| Abstract: |
A new strengthening method of an existing bridge pier by using carbon fibre grid and polymer cement mortar was developed. Carbon fibre grid with a large cross-sectional area will be needed for a strengthening of an existing bridge pier. Therefore, in the strengthening by the new method, two or three layers of carbon fibre grid will be laminated. Accordingly, it is necessary to clarify the mechanical behaviour of both laminated plates of carbon fibre grid with a large cross-sectional area and a reinforced concrete member strengthened by the new method. A four-point static loading test was carried out to investigate the mechanical behaviour of the beams, with three layers of carbon fibre grid, strengthened by the new method. From the test results, it is cleared that bending theory may be used to the reinforced concrete member strengthened by using laminated plates of carbon fibre grid and polymer cement mortar. |
