PROBLEM TO BE SOLVED: To properly evaluate an effect of shear reinforcement of a concrete beam by a reinforcement material, in a construction method for reinforcing the concrete beam with an opening by attaching the reinforcement material.SOLUTION: In a method, an effect of shear reinforcement of a concrete beam with an opening 12 by a CFRP board 14 in a construction method for shear-reinforcing the concrete beam by attaching the CFRP board 14 is evaluated. The effect of the shear reinforcement by the CFRP board 14 is calculated in such a manner as to be further diminished as a distance of an attachment position of the CFRP board 14 in a beam axis direction from the opening 12 becomes longer. |
