PREDICTION OF OCCURRENCE OF CRACKS DUE TO AUTOGENEOUS SHRINKAGE AND DRYING SHRINKAGE
Doboku Gakkai Ronbunshu, 2000 コンクリートのひび割れ発生時期を予測する研究の一環として, 一軸拘束試験体を用いてコンクリートの収縮によりひび割れを発生させ, 各種の要因がひび割れ発生時期に及ぼす影響, ひび割れ発生点近傍のひずみの挙動, 引張伸び能力や収縮応力強度比のひび割れ発生限界点としての適用性などについて検討し, さらに, 逐次解析を行い実験値と解析値の比較を行った. その結果, コンクリートの収縮ひずみが部材内で均一でないことがひび割れ発生時期をばらつかせる原因であること, ひび割れ発生に影響を与えている範囲から算定した引張伸び能力や, 強度発現条件を考慮した収縮応力強度比は, ひび割れ発生時期を予測する限界点として実用上適用できることなどを示した.

The behaviour of reinforced concrete beams under cyclic temperature profiles [PDF]
, 1986 On a hot summer day, high levels of solar radiation are incident on concrete bridge decks, causing non-linear variations in temperature through the depths of the structures. The changes in temperature lead to axial expansion and curvature of decks.
