style="text-indent:25px">現(xiàn)在，國內(nèi)的結(jié)構(gòu)設(shè)計過程中，有這樣的傾向：設(shè)計中考慮強度多而考慮耐久性少；重視強度極限狀態(tài)而不重視使用極限狀態(tài)，而結(jié)構(gòu)在整個生命周期中重要的卻恰恰是使用時的性能表現(xiàn)；重視結(jié)構(gòu)的建造而不重視結(jié)構(gòu)的維護。實際上，目前的橋梁設(shè)計中，對于耐久性更多的只是作為一種概念受到關(guān)注，既沒有明確提出使用年限的要求，也沒有進行專門的耐久性設(shè)計（從材料、結(jié)構(gòu)措施及設(shè)計程序上上保證耐久性，并明確聲明在何種維護和使用條件下，橋梁具有哪種程度的耐久性）。這些傾向在一定程度上導(dǎo)致了當(dāng)前工程事件頻發(fā)、結(jié)構(gòu)使用性能差、使用壽命短的不良后果；也與國際結(jié)構(gòu)工程界日益重視耐久性、安全性、適用性的趨勢相違背；也不符合結(jié)構(gòu)動態(tài)和綜合經(jīng)濟性（考慮結(jié)構(gòu)建設(shè)、使用、維護等整個周期的費用）的要求。 </p><p style="text-indent:25px">鋼結(jié)構(gòu)橋梁的優(yōu)點：鋼材的抗拉、抗壓、抗剪強度相對來說較高，鋼構(gòu)件斷面小、自重輕。鋼材的塑性和韌性好，使鋼結(jié)構(gòu)橋梁的抗震性能好。施工工期短。鋼結(jié)構(gòu)的材料加工簡易而迅速；材料的運輸量少，施工現(xiàn)場占地面積小，連接簡便，安裝方便，施工周期短。鋼結(jié)構(gòu)是環(huán)保產(chǎn)品。舊部件可重新熔煉，可節(jié)約能源，符合可持續(xù)發(fā)展的政策。　　鋼結(jié)構(gòu)橋梁適用范圍廣。鋼混結(jié)構(gòu)適用于500m以下跨度的拱橋和斜拉橋，不適用于懸索橋；鋼結(jié)構(gòu)橋適用于不同跨度的拱橋、懸索橋和斜拉橋，特別是大跨度的懸索橋。鋼橋質(zhì)量容易保證。鋼橋的優(yōu)點是連接簡便，安裝方便。</p><div
