First, based on the analysis to the development condition of computer and property of the input data of bridge, this paper, taking convenience and practicability as principle, develops the multi passages data-in system made up with human-computer interactive interface and excel import model . second, after comparing and analyzing to the calculation theories and methods of creep and shrinkage, clearing up the key steps of creep and shrinkage analysis, the paper takes incremental method to establish program to analyze secondary inner force caused by creep and shrinkage . third, the paper puts some optimal or simplified treatment to the contents of pre-stress and develops relative program; in addition, through analysis to the different methods used to calculate the secondary inner force caused by pre-stress, the paper combines equivalent load method with finite element, carries out some simplified treatments, and establishes program to calculate secondary inner force caused by pre-stress 首先,在分析當(dāng)前計算機的發(fā)展?fàn)顩r及橋梁結(jié)構(gòu)輸入數(shù)據(jù)特點的基礎(chǔ)上,以方便、實用為原則,采用人機交互界面和excel輸入方式聯(lián)合的多通道數(shù)據(jù)輸入系統(tǒng);其次,通過比較分析徐變收縮計算的各種理論及方法,澄清了徐變收縮分析的關(guān)鍵過程,并采用增量法編制程序,實現(xiàn)徐變收縮次內(nèi)力分析;再次,對預(yù)應(yīng)力的相關(guān)計算內(nèi)容進行適當(dāng)優(yōu)化或簡化處理,并編制相應(yīng)程序;另外,本文還在比較預(yù)應(yīng)力次內(nèi)力各種計算方法的基礎(chǔ)上,將等效荷載法結(jié)合有限元進行一些簡化處理,編制程序?qū)崿F(xiàn)預(yù)應(yīng)力次內(nèi)力的計算;最后以三個算例來校核計算方法及程序運行結(jié)果的可靠性,取得了預(yù)期效果。
