DETERMINATION METHOD AND CONSTRUCTION METHOD
To provide a method for determining the necessity of a crack suppression member capable of rationally suppressing the crack of a concrete structure by appropriately arranging the crack suppression member and a method for constructing the concrete structure.SOLUTION: A determination method according to one embodiment is the determination method for determining the necessity of a crack suppression member embedded in the concrete 8. A determination method comprises the steps of: placing concrete 8 in a concrete placing area A by placing optical fiber sensors 11 at multiple positions in the concrete placing area A; measuring distortion amounts at the plurality of positions by the optical fiber sensors 11 after placing the concrete 8; and determining the necessity of the crack suppression member from the magnitude of the difference between the distortion amounts at the plurality of positions.SELECTED DRAWING: Figure 3
【課題】ひび割れ抑制部材の配置を適切に行ってコンクリート構造物のひび割れを合理的に抑制できるひび割れ抑制部材の要否の判定方法、及びコンクリート構造物の構築方法を提供する。【解決手段】一実施形態に係る判定方法は、コンクリート８の内部に埋設されるひび割れ抑制部材の要否を判定する判定方法である。判定方法は、コンクリート打設域Ａの複数の位置に光ファイバセンサ１１を配置してコンクリート打設域Ａにコンクリート８を打設する工程と、コンクリート８の打設後に光ファイバセンサ１１が当該複数の位置の歪み量を測定する工程と、当該複数の位置の歪み量の差分の大きさからひび割れ抑制部材の要否を判定する工程と、を備える。【選択図】図３
