style="text-indent:25px">鋼橋設(shè)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(yīng)力狀態(tài)、連接的構(gòu)造與方法、構(gòu)造細節(jié)等。鋼橋的設(shè)計必須選用有足夠韌性的鋼材，盡可能避免應(yīng)力集中和容易出現(xiàn)疲勞的構(gòu)造細節(jié)、連接構(gòu)造與方法。結(jié)構(gòu)在其傳力途徑中的截面變化的緩急程度是影響應(yīng)力集中的主要因素，鋼橋設(shè)計中應(yīng)該避免截面的急劇變化。如T形連接中盡可能設(shè)置曲線過渡段，避免出現(xiàn)隅角。鋼橋設(shè)計不僅要滿足使用階段的受力和工作性能要求，而且應(yīng)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(yīng)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(yù)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(shè)備及結(jié)構(gòu)本身都應(yīng)按起頂重力增加30％驗算。美觀上的要求。在滿足上述要求的前提下，盡可能使橋梁具有優(yōu)美的建筑外型。深圳正規(guī)鋼橋深化設(shè)計下載</p><p
