style="text-indent:25px">鋼橋設(shè)計(jì)一般要求和原則：鋼橋一般用鋼板、型鋼等加工制作而成，加工工序多，工藝復(fù)雜，要求較高的技術(shù)和工廠專業(yè)化生產(chǎn)。為了便于控制和保證鋼橋的質(zhì)量，鋼橋一般采用工廠焊接構(gòu)件，工地現(xiàn)場(chǎng)拼裝（**螺栓連接或工地焊接）。鋼結(jié)構(gòu)設(shè)計(jì)要與架設(shè)方案統(tǒng)籌考慮，應(yīng)以經(jīng)濟(jì)合理、便于加工、方便運(yùn)輸安裝和檢查維護(hù)為準(zhǔn)。鋼橋是**、輕型薄壁結(jié)構(gòu)，截面和自重比混凝土橋小，跨越能力大。同時(shí)，鋼橋的剛度相對(duì)較小，變形和振動(dòng)比混凝土橋大。為了保證車輛行駛安全和舒適性、避免過大的變形和振動(dòng)對(duì)鋼橋結(jié)構(gòu)產(chǎn)生不利的影響，鋼橋必須有足夠的整體剛度。規(guī)范規(guī)定，由汽車荷載所引起的豎向撓度（deflection），不應(yīng)超過一定的容許值。</p><p style="text-indent:25px">鋼橋是一種橋跨結(jié)構(gòu)用鋼材建造的橋梁。1874年美國(guó)在密西西比河上建造了世界上首座大型鋼橋——圣路易斯(St.Louis)鋼拱橋，第二次世界大戰(zhàn)以后，鋼橋科學(xué)技術(shù)在**質(zhì)量鋼的冶煉，焊接技術(shù)的提高，正交異性鋼橋面板和**螺栓的應(yīng)用，以及結(jié)構(gòu)型式的多樣化等方面，有了很大的發(fā)展，促使大跨度鋼橋的普遍采用。由于鋼材強(qiáng)度高，性能優(yōu)越，表觀密度與容許應(yīng)力之比值小，故鋼橋跨越能力較大。鋼橋的構(gòu)件制造較適合工業(yè)化，運(yùn)輸與安裝均較方便，架設(shè)工期較短，破壞后易修復(fù)和更換，但鋼材易銹蝕，養(yǎng)護(hù)困難。在恒載作用下，橋梁結(jié)構(gòu)會(huì)產(chǎn)生變形，為了保證鋼橋成橋后的橋面線形盡可能與線路設(shè)計(jì)線形一致。</p><div
