style="text-indent:25px">國內(nèi)從上世紀90年代開始重視了對結(jié)構(gòu)耐久性的研究，也取得了不少成果。這些研究大多是從材料和統(tǒng)計分析的角度進行的，對如何從結(jié)構(gòu)和設(shè)計的角度及如何以設(shè)計和施工人員易于接受和操作的方式來改善橋梁耐久性卻很少有人研究。而且，長期以來，人們一直偏重于結(jié)構(gòu)計算方法的研究，卻忽視了對總體構(gòu)造和細節(jié)處理方面的關(guān)注。結(jié)構(gòu)的耐久性設(shè)計與常規(guī)的結(jié)構(gòu)設(shè)計有著本質(zhì)的區(qū)別，目前需要努力將耐久性的研究從定性分析向定量分析發(fā)展。國外的鋼橋設(shè)計有鑒于耐久性不足導致的嚴重損失，近年來十分重視提高結(jié)構(gòu)物的耐久性并將其作為重要的設(shè)計原則，統(tǒng)一考慮合理的結(jié)構(gòu)布局和構(gòu)造細節(jié)，強調(diào)使結(jié)構(gòu)易于檢查、維修，以保證鋼橋的安全使用、盡可能地減少維修費用，取得了較好的綜合經(jīng)濟效益。實際上，國內(nèi)外的研究和實踐都表明，結(jié)構(gòu)耐久性對于橋梁的安全運營和經(jīng)濟性起著決定性作用。鋼橋一般用鋼板、型鋼等加工制作而成。</p><div
