（中國建筑科學研究院建筑結(jié)構(gòu)研究所 北京 100013）[提要] 本文在適筋混凝土構(gòu)件正截面配筋的物理界限條件下進一步作了概率分析，上限條件仍以相對界限受壓區(qū)高度表示，下限條件仍以受拉鋼筋最小配筋率表示，匕們分別按0.15和0.85分位數(shù)作為取值的依據(jù)，以策安全。
[關(guān)鍵詞] 配筋界限 少筋 適筋 超筋 混凝土構(gòu)件Under the physical boundary condition for reinforcement of normal section on under-reinforced concrete member, a probability analysis is further presented, its upper limited condition was shown by the relative boundary height of compression zone and lower limited condition was shown by the mimmum reinforcemet ratio, they were in accordance with their'fractiles of O.15 and O.85 respectively as a basis to take their design value for sake of ensuring the safety of member.
Keywords: reinforcement boundary; rare (or lightly) -reinforced concrete; under-reinforced concrete; over-reinforced concrete; concrete member
