PROBLEM TO BE SOLVED: To provide a shear reinforcement method which can be performed even when a working space is narrow.SOLUTION: The shear reinforcement method is a method for increasing shear capacity of an existing reinforced concrete structure. The method comprises steps of; drilling a plate-shaped insertion hole 2 in a RC wall 1; inserting a shear reinforcement material 3 having flexibility and a plate shape into the insertion hole; and filling the insertion hole with a filler 4, which can be conducted before or after the step of inserting the shear reinforcement material. Here, the shear reinforcement material can have such a structure as to have a fixing portion 3a which is formed at at least one end in a depth direction of the insertion hole so as to protrude toward an out-of-plane direction. |
