Bailey)工程師在1938年第二次世界大戰(zhàn)初期設(shè)計(jì)的。鋼構(gòu)橋自身主要的設(shè)計(jì)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(yùn)輸，特殊情況下能全部依靠人力來(lái)搭建。方便快捷，且較為耐用。 </p> <p> <br /> </p><p style="text-indent:25px">鋼橋設(shè)計(jì)一般要求和原則：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，當(dāng)恒載撓度較大時(shí)，橋跨結(jié)構(gòu)應(yīng)設(shè)預(yù)拱度（Camber）。公路鋼橋規(guī)范規(guī)定，當(dāng)結(jié)構(gòu)重力和靜活載產(chǎn)生的豎向撓度超過(guò)跨徑的1/1600時(shí)，應(yīng)設(shè)預(yù)拱度，其值等于結(jié)構(gòu)重力與1/2靜活載產(chǎn)生的豎向撓度之和，起拱應(yīng)做成平順曲線。如橋面在豎曲線上，預(yù)拱度應(yīng)與豎曲線縱坡一致。對(duì)于鋼橋采用工地焊接時(shí)，還必須考慮由于焊接產(chǎn)生的結(jié)構(gòu)變形。特別是當(dāng)鋼橋面板采用焊接，鋼梁底板和腹板采用螺栓連接的混和連接結(jié)構(gòu)形式橋梁，在支架上無(wú)應(yīng)力狀態(tài)連接時(shí)，焊接產(chǎn)生的變形較大，甚至接近或超過(guò)恒載撓度。橋梁一般由上部構(gòu)造、下部結(jié)構(gòu)和附屬構(gòu)造物組成。</p><div
