鉄筋コンクリートにプレストレスを導入した(PRC)部材のせん断ひび割れについて以下のことが明らかとなった.1) せん断ひび割れ幅は、せん断補強筋補強筋ひずみと強い相関を示す.2) せん断ひび割れ幅は、RCにおいてはコンクリートの圧縮強度の影響は見られないが、PRCにおいては小さくなる.3) せん断ひび割れ幅を水平および垂直成分に分解して、せん断補強筋ひずみを用いることによって、かなりの精度でRCおよびPRCはり部材のせん断ひび割れ幅を計算出来る手法を開発した.

The influence of the compression strength of the steel reinforcement on the strength of the steel reinforcement is shown in the following ways: (1) the strength of the steel reinforcement is shown in the following ways: (2) the strength of the steel reinforcement is shown in the following ways: (3) the strength of the steel reinforcement is shown in the following ways: (4) the strength of the steel reinforcement is shown in the following ways: (5) the strength of the steel reinforcement is shown in the following ways: (6) the strength of the steel reinforcement is shown in the following ways: (7) the strength of the steel reinforcement is shown in the following ways: (8) the strength of the steel reinforcement is shown in the following ways: (9) the strength of the steel reinforcement is shown in the following ways: (10) the strength of the steel reinforcement is shown in the following ways: (10) the strength of the steel reinforcement is shown in the following ways: (10) the strength of the steel reinforcement is shown in the strength of the steel reinforcement is shown in the following ways: (10) the strength of the steel reinforcement is shown in the strength of the steel reinforcement is shown in The method for calculating the horizontal and vertical components of the RC and PRC components is developed.
