Bailey）工程師在1938年第二次世界大戰(zhàn)初期設(shè)計。主要的設(shè)計概念是以較少種類的單元構(gòu)件，拼裝成能承載各種荷載、不同跨徑的裝配式鋼橋，且只需一般中型卡車運輸，特殊情況下并能全部以依靠人力來搭建。在第二次世界大戰(zhàn)期間，裝配式鋼橋被大量用于歐洲及遠(yuǎn)東戰(zhàn)場，搶修橋梁或架設(shè)臨時便橋。美國于1941年從英國購買了**，制造裝配式鋼橋，命名為M1型；經(jīng)過改進(jìn)后（車行道加寬12%），命名為M2型。二戰(zhàn)后，許多國家引進(jìn)了裝配式鋼橋，并開始普遍泛應(yīng)用于民用。在中國，裝配式鋼橋也得到了很大發(fā)展，并于1965年定型生產(chǎn)，現(xiàn)普遍應(yīng)用于**戰(zhàn)備、交通工程、市政水利工程。北京好的鋼橋設(shè)計企業(yè)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><div

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)費用高。鋼橋自身的主要特點是：1、跨越能力大。2、合適無工業(yè)化制造。3、便于運輸。4、安裝速度快。5、鋼橋構(gòu)件易于修復(fù)和更換。6、鋼材易腐蝕，故鋼橋的養(yǎng)護(hù)費用高。 </p><p 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(dá)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(jìn)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(zāi)害的能力（尤其抗地震災(zāi)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(biāo)（建設(shè)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。韌性、延性好，可提高抗震性能。</p><div

style="text-indent:25px">纜索懸吊法懸索橋的施工,通常是先架設(shè)纜索,用纜索上臨時加設(shè)的走行吊架，將加勁梁的梁段逐漸提升，懸掛在纜索垂下的吊桿上，調(diào)整位置后拼裝成整跨的加勁梁。施工時加勁梁梁段的自重，由纜索承受。美國的金門、韋拉扎諾海峽及英國的亨伯等不錯的懸索橋（見彩圖），均用這種方法施工。瑞典阿斯克勒峽灣(Asker Fjord)鋼管拱橋（1960年）,利用同一原理提升跨度278米的管拱節(jié)段，懸吊在臨時施工的纜索下，調(diào)整位置后拼鉚成拱，整體降落到支座上。拱、梁組合結(jié)構(gòu)，也可采用此法安裝架設(shè),如日本天草二號橋（1966年）的156.8米朗格爾桁架梁，就是這樣施工的。北京好的鋼橋設(shè)計企業(yè)</p><p
