（中國建筑技術(shù)研究院 北京 100044）[提要] 對預(yù)應(yīng)力和部分預(yù)應(yīng)力混凝土柱軸壓比限值計算公式進行了理論推導(dǎo)，并計算出具體數(shù)值，與普通鋼筋混凝土柱進行了對比分析，同時還指出了有關(guān)影響因素?？晒┰O(shè)計地震區(qū)預(yù)應(yīng)力和部分預(yù)應(yīng)力混凝土柱時參考。
[關(guān)鍵詞] 預(yù)應(yīng)力混凝土 柱 軸壓比 抗震設(shè)計The calculate formula of the limitation for axial compressive force N and bhfe of the prestressed and partially prestressed concrete column was theoretically developed, and the detailed count was computed in this article. The compare with reinforced concrete column was analyzed, also the relative affecting factors had been indicated in this article. These results can be referenced for the design of PC and PPC column.
Keywords: partially prestressed concrete; column; axial compression ratio
