In this study, a new numerical method of pipe-cooling thermal analysis is presented in order to achieve arbitrary layout of the cooling pipe independent of FEM mesh arrangement. Then, some thermal analyses for concrete structural model with pipe cooling system are executed and validity of the proposed numerical method is discussed. As a result, it is confirmed that the proposed analytical procedure can simulate quite rational temperature histories despite of the cooling pipe layout independent of FEM mesh arrangement.

本研究では, 荷重履歴による間隙水圧特性の詳細な評価を行うことを目的として, 繰り返し荷重下における間隙水圧特性に関する実験的および解析的評価を行った. まず, 前報で報告した横方向変位拘束型である一次元圧密状態を摸擬した間隙水圧測定用セルを用い, 載荷材齢をパラメータとした実験を実施し, 繰り返し荷重下の間隙水圧特性を論じるとともに実験パラメータが間隙水圧特性に及ぼす影響を検討した. そして, 筆者等が構築した水・コンクリート骨格連成解析手法を時間依存型挙動に対しても適用可能なように拡張し, 繰り返し荷重下のコンクリート応力に及ぼす間隙水圧の影響評価を解析的にも実施した.
