- 論文の詳細を見る
The aim of this study is to get the spatial average stress- average strain relationships of both reinforcing bars and cracked concrete in RC members based on the local bond characteristics between concrete and re-bars. The computational basis is the local bond-slip-strain model [3]. In the computation the local stress and strain profiles of both re-bars and concrete between two adjacent cracks are computed. Using these profiles, the spatial average stress and average strains can be computed. The computation is also capable of predicting the ultimate average strain of re-bars. The comparison with the experiments shows good agreement.
