style="text-indent:25px">鋼橋設計一般要求和原則：鋼橋的另一缺點是疲勞。影響鋼橋疲勞的主要因素有：鋼材品質(zhì)、荷載性質(zhì)、應力狀態(tài)、連接的構造與方法、構造細節(jié)等。鋼橋的設計必須選用有足夠韌性的鋼材，盡可能避免應力集中和容易出現(xiàn)疲勞的構造細節(jié)、連接構造與方法。結構在其傳力途徑中的截面變化的緩急程度是影響應力集中的主要因素，鋼橋設計中應該避免截面的急劇變化。如T形連接中盡可能設置曲線過渡段，避免出現(xiàn)隅角。鋼橋設計不*要滿足使用階段的受力和工作性能要求，而且應分析施工吊裝和調(diào)整支座等受力狀況，使鋼橋在施工過程中滿足應力和變形的要求。考慮到吊裝過程中的慣性作用和其他不可預見的不利因素影響，公路鋼橋規(guī)范規(guī)定，鋼橋施工驗算時起頂設備及結構本身都應按起頂重力增加30％驗算。北京鋼橋計算哪家好在通航河道上，應滿足航運的要求。</p><div

style="text-indent:25px">鋼橋發(fā)展的重要前提和淺見：設計大師邵長宇指出“橋梁技術的發(fā)展都離不開材料，但就鋼橋發(fā)展來說，國內(nèi)橋梁用鋼的發(fā)展還有待突破……”。那就是鋼梁的材質(zhì)應具有**度、高堅韌性、高淬透性、低碳且塑性好并具有高性價比的環(huán)保材料的特點，一般稱之為高性能鋼（HPS）,如今，我國鋼材產(chǎn)量和質(zhì)量比過去提高很多，但在材料的品種、規(guī)格和性能的多用途上與國外還有較大的差距，因而在一定程度上成了影響著橋梁結構的設計和施工工藝的瓶頸。所以橋梁的質(zhì)量、耐久性和跨度的大小與鋼材的創(chuàng)新是密切相關的。</p><p style="text-indent:25px">不同瀝青鋪裝材料用于鋼橋面鋪裝，不*在性能上而且在施工工藝以及在工程造價上，都有明顯的區(qū)別。從許多國家實際應用情況來看，在使用性能和使用壽命方面，以環(huán)氧瀝青鋪裝較好，澆注式瀝青和SMA次之，普通瀝青較差。在施工工藝方面，環(huán)氧瀝青混合料拌制工藝雖不是太復雜，但對溫度、時間控制非常嚴格；澆注式瀝青工藝比較特別，需要特殊的拌制設備；SMA只是比普通瀝青路面復雜一些。在工程造價方面，如以同樣厚度相比較，則環(huán)氧瀝青鋪裝成本較高，澆注式瀝青鋪裝次之，SMA比普通瀝青費用約增加20%～30%，但比環(huán)氧瀝青和澆注式瀝青為低。然而，環(huán)氧瀝青因強度高，鋪裝層因此可以減薄，減輕了自重，又有利于降低造價；澆注式瀝青鋪裝層厚度也較薄，或與普通瀝青鋪裝復合使用。橋梁設計必須積極采用新結構、新毆備、新材料。</p><div

style="text-indent:25px">中國目前發(fā)展鋼橋的機遇和展望：（1）目前我國鋼橋的數(shù)量*占全部橋梁總數(shù)的百分之一左右，而我國2010年的鋼產(chǎn)量已達到6.3億噸，占全球鋼產(chǎn)量的百分之四十四以上，已成了全球鋼材產(chǎn)量的大國。進入2011年，我國日均194萬噸的產(chǎn)量記錄，年均7億噸的粗鋼產(chǎn)量，以及百分之九十以上的產(chǎn)能利用率，更將為發(fā)展鋼橋提供了有力的支撐平臺。（2）從制造速度、耐久性、抗自然災害的能力（尤其抗地震災害的能力）與砼橋梁比較,具有突出的優(yōu)勢。從綜合經(jīng)濟和社會效益指標（建設速度、施工裝備與安全、質(zhì)量控制難度、維修頻率及費用、耐久壽命、環(huán)保條件……）比較，必將有突破的趨勢?？s短工期不*能降低施丁費用，而且盡早通車在運輸上將帶來很大的經(jīng)濟效益。北京鋼橋計算哪家好</p><p
