翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Crack spacing of reinforced concrete ： ウィキペディア英語版 Crack spacing of reinforced concrete Concrete is a brittle material and can only withstand small amount of tensile strain due to stress before cracking. When a reinforced concrete member is put in tension, after cracking, the member elongates by widening of cracks and by formation of new cracks. Ignoring the small elastic strain in the concrete between the cracks, we can relate the crack width to the strain of the member by: :$\_=\; \backslash epsilon\_s\_m$ ==Spacing of Primary cracks== Primary cracks (Figure 1) form when the tensile stress at the outer surface of the concrete reaches the tensile strength of concrete. When a primary crack forms, the concrete in the vicinity of the crack is relieved of any tension, resulting in a stress free zone near the crack. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Crack spacing of reinforced concrete」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
