style="text-indent:25px">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)場拼裝（**螺栓連接或工地焊接）。鋼結(jié)構(gòu)設(shè)計要與架設(shè)方案統(tǒng)籌考慮，應(yīng)以經(jīng)濟合理、便于加工、方便運輸安裝和檢查維護為準。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，鋼橋的剛度相對較小，變形和振動比混凝土橋大。為了保證車輛行駛安全和舒適性、避免過大的變形和振動對鋼橋結(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，不應(yīng)超過一定的容許值。北京好的鋼橋深化哪家好鋼橋的優(yōu)點是鋼結(jié)構(gòu)的材料加工簡易。</p><div

style="text-indent:25px">鋼橋設(shè)計建議:刻意追求美觀，強力硬拽往往會畫蛇添足，適得其反。就拿通常的天橋來說，在山區(qū)或平原區(qū)或城市附近都很有講究，在地形地勢復(fù)雜的山區(qū)道路上，構(gòu)造簡單輕盈的上跨橋便足夠了；而平坦廣闊又有景觀需求的地方往往需要通過上跨橋的造型予以彌補；在城市附近，人車流量大的地方，上跨結(jié)構(gòu)無論是上部結(jié)構(gòu)造型還是下部的構(gòu)造形式都應(yīng)充分重視，甚至橋上的具體裝飾物都應(yīng)無微不至。從根本意義上來說。橋的美觀性應(yīng)該是在平和、自然中又賦予靈動。</p><p style="text-indent:25px">鋼橋與鋼混凝土橋的不同之處：雖然鋼橋的強度大，但它抗腐蝕性較弱，所以不僅要細心選材，還需要經(jīng)常檢查和維修，費用較高。與鋼筋混凝土橋相比，鋼橋能降低自身梁高和減少自身重量=我們熟悉的武漢長江大橋、南京長江大橋、杭州灣大橋都是鋼橋。鋼筋混凝土橋形成于19世紀后半葉，雖然鋼筋混凝土橋出現(xiàn)較晚，但自出現(xiàn)以來不到200年時間就已經(jīng)被普遍建設(shè)，鋼筋混凝土橋的發(fā)展速度之快有目共睹。鋼筋混凝土橋的主要材料——鋼筋混凝土并非從一開始就被作為橋梁的重要建材使用，它初常用于修建水壩、管道和樓板，直至1875年，法國園藝師才主持建成了一座鋼筋混凝土橋，可惜的是該橋早已不存在了。假如需要架建中小型跨度的橋梁，鋼筋混凝土橋是不錯選擇。假如需要架建跨度較大的橋梁，則選擇鋼橋更合適。鋼橋的主要優(yōu)點有受拉、壓、彎、剪均可。</p><div
