[關(guān)鍵詞] 適筋混凝土 少筋混凝土 最小配筋率 極限狀態(tài)The paper introduces briefly the design method of rare - reinforced concrete member in the main relevant codes at home and abroad, and all those were reviewed through comparsion, hence an additional coefficient formula is summed up, which is applicable for brittle failure of rare - reinforced concrete flexural member under different requirements and can be used as a component part of structural importance factor to facilitate the design.
Keywords: under - reinforced concrete; rare(or lightly) - reinforced concrete; minimum reinforcement
