由于鋼材的各向同性，質(zhì)地均勻及彈性模量大，使橋的工作情況與計(jì)算圖示假定比較符合，另外鋼橋一般采用工廠預(yù)制，工地拼接，施工周期短，加工方便且不受季節(jié)影響。但鋼橋的耐火性，耐腐蝕性差，需要經(jīng)常檢查，維修，養(yǎng)護(hù)費(fèi)用高。鋼橋自身的主要特點(diǎn)是：1、跨越能力大，鋼橋繪圖哪家好。2、合適無工業(yè)化制造。3、便于運(yùn)輸。4、安裝速度快。5、鋼橋構(gòu)件易于修復(fù)和更換。6，鋼橋繪圖哪家好、鋼材易腐蝕，鋼橋繪圖哪家好，故鋼橋的養(yǎng)護(hù)費(fèi)用高。鋼橋在工地的安裝速度也快。鋼橋繪圖哪家好</p><div

style="text-indent:25px">鋼橋是一種橋跨結(jié)構(gòu)用鋼材建造的橋梁。1874年美國在密西西比河上建造了世界上一座大型鋼橋——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**較好鋼的冶煉，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。鋼橋具有很大的跨越能力。橋梁跨度非常大、荷載非常重。上海鋼橋深化設(shè)計(jì)服務(wù)</p><p
