PROBLEM TO BE SOLVED: To allow for manufacturing of a reinforced concrete specimen in which cracks conforming to an actual state have occurred.SOLUTION: In a step S101, a flexural load is applied to a first surface of a reinforced concrete piece in such a state that tensile stress occurs. In a step S102, the occurrence of a crack in the first surface is conformed. When the occurrence of the crack is confirmed in the step S102 (y in the step S102), the operation to apply the flexural load to the first surface is stopped to release the load on the first surface in a step S103. Next, in a step S104, a flexural load is applied to a second surface opposite to the first surface of the reinforced concrete piece in such a state that tensile stress occurs. In a step S105, the occurrence of a crack in the second surface is confirmed. |
