SOLUTION: A plurality of anchor bolts 14 are driven in the peripheral part of an opening part 12 formed in an existing beam 10, and reinforcement fiber strands 16 are stretched across and wrapped around the two anchor bolts 14. In place of driving the anchor bolts, through holes may be formed. In the other embodiment, a steel plate is installed on the lower surface of the existing beam 10, and the fiber strands 16 are stretched across and wrapped around the steel bar installed on the underside of the steel plate and the anchor bolts 14. When a concrete wall having a rectangular opening is reinforced, the fiber strands 16 are wrapped around near the corner part of the opening in the same manner as indicated above.
