[關(guān)鍵詞] 鋼筋混凝土 配筋構(gòu)造 縱向鋼筋最小配筋率Background to provisions in Cocle for cleszgn o[concrete structures with regard to minimum longitudinal reinforcement ratio in RC members is presented. The function and evaluation of mlnlmum longitudinal reinforcement ratio both under compression and tension are analysed. On the basis of comparison with foreign codes, discussions on the level of evaluation of minimum reinforcement ratio in the revised code are given, along with other remaining problems.
Keywords: reinforced concrete; reinforcement detailing; minimum longitudinal reinforcement ratio
