Calculations of flexural strengths for reinforced concrete beams repaired with CFRP |
| |
| Abstract: | Based on the general assumptions for the ultimate flexural strengths of reinforced concrete beams, the (equations) of the ultimate resistance moments of the concrete flexural members repaired with carbon fiber reinforced polymer were proposed for the design calculations. The effect of the secondary loads of the repaired members was considered in the derived equations. The equations were applied to calculate the repaired beams given in the (references). The agreement between the theoretical and the experimental results was desirable. It showed that the (equations) derived in the paper were applicable to the design calculations in practical engineering. |
