style="text-indent:25px">許多設(shè)計人員往往只滿足于規(guī)范對結(jié)構(gòu)強(qiáng)度計算上的安全度需要，而忽視從結(jié)構(gòu)體系、結(jié)構(gòu)構(gòu)造、結(jié)構(gòu)材料、結(jié)構(gòu)維護(hù)、結(jié)構(gòu)耐久性以及從設(shè)計、施工到使用全過程中經(jīng)常出現(xiàn)的人為錯誤等方面去加強(qiáng)和保證結(jié)構(gòu)的安全性。有的結(jié)構(gòu)整體性和延性不足，冗余性??；有的計算圖式和受力路線不明確，造成局部受力過大；有的混凝土強(qiáng)度等級過低、保護(hù)層厚度過小、鋼筋直徑過細(xì)、構(gòu)件截面過薄；這些都削弱了結(jié)構(gòu)耐久性，會嚴(yán)重影響結(jié)構(gòu)的安全性。不少鋼橋、雖然滿足了設(shè)計規(guī)范的強(qiáng)度要求，*用了5年就因為耐久性出了問題影響結(jié)構(gòu)安全。結(jié)構(gòu)耐久性不足已成為現(xiàn)實的一個安全問題，設(shè)計時要從構(gòu)造、材料等角度采取措施加強(qiáng)結(jié)構(gòu)耐久性。 </p><p style="text-indent:25px">鋼橋小知識：為了防止鋼橋的橫向失穩(wěn)和過大的橫向振動，橋梁結(jié)構(gòu)應(yīng)具有必要的橫向剛度。特別是鐵路鋼橋，往往是橋?qū)捿^窄、活載大、列車的蛇行運動容易產(chǎn)生橫向振動，橫向穩(wěn)定問題較為突出。在特大跨度公路鋼橋中，寬跨比減小，也有可能出現(xiàn)橫向失穩(wěn)，特別是大跨度鋼拱橋，應(yīng)該從構(gòu)造和結(jié)構(gòu)尺寸兩方面保證結(jié)構(gòu)的橫向穩(wěn)定。通常，跨長超過橋?qū)挼?0倍時，應(yīng)該驗算橋梁結(jié)構(gòu)的橫向穩(wěn)定。橋跨結(jié)構(gòu)在施工架設(shè)時期也應(yīng)保證橫向和縱向的傾覆穩(wěn)定性。公路鋼橋規(guī)范規(guī)定，穩(wěn)定系數(shù)應(yīng)不小于1.3。鋼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。</p><div
