style="text-indent:25px">鋼橋小知識(shí)：鋼橋設(shè)計(jì)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(guò)程中滿足應(yīng)力和變形的要求。考慮到吊裝過(guò)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(yàn)算時(shí)起頂設(shè)備及結(jié)構(gòu)本身都應(yīng)按起頂重力增加30％驗(yàn)算。鋼橋的一缺點(diǎn)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(xì)節(jié)等。鋼橋的設(shè)計(jì)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(xì)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(jì)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(guò)渡段，避免出現(xiàn)隅角。</p><p style="text-indent:25px">調(diào)查得到的荷載譜不可能包括所有的車型，只是主要反映出現(xiàn)率較高的典型車型，但按軸數(shù)、軸距、荷重之分一般仍多達(dá)十幾種，疲勞驗(yàn)算時(shí)計(jì)算工作量很大，故可作進(jìn)一步的簡(jiǎn)化處理，方法有：（1）用一輛標(biāo)準(zhǔn)疲勞車來(lái)表示荷載譜，即對(duì)原荷載譜中各種車輛對(duì)鋼橋造成的疲勞損傷進(jìn)行分析，以損傷嚴(yán)重的車輛為藍(lán)本，提煉出一輛標(biāo)準(zhǔn)疲勞車。原譜中各種車輛的荷重用其與疲勞車荷重之比來(lái)表示。這樣驗(yàn)算時(shí)通過(guò)疲勞車的一次加載就能成比例地推算到原譜中各種車輛一次加載所產(chǎn)生的應(yīng)力狀況，英國(guó)BS5400采用了此簡(jiǎn)化方法。（2）用幾種模型車輛的荷載譜來(lái)表示原荷載譜，即將原譜中各種車輛按相同的軸數(shù)合并歸類，根據(jù)等效的疲勞損傷原理分別將各類別中的幾種車輛等效成一種模型車輛。鋼橋一般用鋼板、型鋼等加工制作而成。</p><div
