[提要] 預(yù)應(yīng)力將在超靜定結(jié)構(gòu)中產(chǎn)生次內(nèi)力。在具有任意曲線形狀的預(yù)應(yīng)力筋和沿預(yù)廖力筋縱向具有任意分布的預(yù)應(yīng)力所產(chǎn)生的桿單元固端次內(nèi)力計算積分表達(dá)式的基礎(chǔ)上，探討了固端次內(nèi)力計算程序的設(shè)計方法，可為工程設(shè)計計算提供快捷而有效的工具。
[關(guān)鍵詞] 預(yù)應(yīng)力桿 固端次內(nèi)力 特征數(shù)組 程序框圖Prestress will cause secondary internal force in statically indeterminate structures. Based on the for-mula of calculating the secondary internal force at the fixed end of prestrese - element due to pre-stressing with any initial shape of prestressing cable and any distribution of prestress along the ca-ble, a programming method has been discussed which provides a direct and effective means for de-sign and compution.
Keywords: prestress element; secondary internal force; fixed bearings; characteristic dimension;
program; design
