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，鋼橋深化服務企業(yè)，鋼橋深化服務企業(yè)，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，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，鋼橋深化服務企業(yè)，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。鋼橋設計的時候要具有必要的橫向剛度。鋼橋深化服務企業(yè)</p><div

style="text-indent:25px">隨著時代經(jīng)濟的高速發(fā)展，人類建造的各種大型工程規(guī)模巨大，結(jié)構(gòu)復雜，功能眾多。這些工程投資巨大，技術復雜，環(huán)境影響嚴重，襲擊破壞幾率增大（風、浪、地震、海嘯、船撞等），維修、養(yǎng)護、加固難度大。因而，過去只限于從設計、施工質(zhì)量的單一層面上去尋求結(jié)構(gòu)的安全性是不夠的?；诮Y(jié)構(gòu)耐久性設計的新設計理念認為，橋梁耐久性的保證是需要橋梁設計、施工、運營和維護各個階段共同努力的結(jié)果。目前設計標準定義的均是設計建成時期結(jié)構(gòu)具有的使用性能，而對處于使用狀態(tài)的性能隨時間的變化卻缺乏充分的認識和儲備，簡單講，似乎只考慮了建造期造價成本，卻忽視了運營期的維護成本和與使用壽命相對應的成本效益，這與可持續(xù)發(fā)展的觀點是相背的。在接踵而來的改擴建工程設計中可以深刻地體會到這一點。鋼橋深化服務企業(yè)鋼橋的優(yōu)點是連接簡便，安裝方便。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鋼橋深化服務企業(yè),鋼橋"

style="text-indent:25px">安全是鋼橋結(jié)構(gòu)設計的前提：隨著改變開放的力度加大，城市車輛的飛速發(fā)展，城市交通運輸十分繁忙，車速也在不斷提高，橋梁結(jié)構(gòu)不光要求結(jié)構(gòu)自身的受力安全，而且要求橋梁構(gòu)造的安全。在作樂山市大渡河龔嘴電站大橋設計中，我們設計組也進行了許多方案比選，有河中設墩的連續(xù)箱梁，有連續(xù)剛構(gòu)，有上承式拱橋等橋梁結(jié)構(gòu)形式。根據(jù)實際的地形、地質(zhì)、地物，后綜合比較選擇了中承式拱橋，一跨135米跨過，保證了急流的大渡河流水斷面和橋梁結(jié)構(gòu)自身安全（該橋驗算荷載為特種荷載-300，已于1999年10月通車，并進行了動、靜載實驗，運行良好）。又如在大營坡立交橋設計中，橋墩是采用圓柱還是方柱問題上，我們設計組也進行了結(jié)構(gòu)分析和討論，終一致選擇用方柱，保證橋墩的結(jié)構(gòu)剛度（因上部結(jié)構(gòu)傳下的偏心彎矩較大），方柱的四角采用了R15cm的圓角，以盡量減少橋下車輛對橋墩摩擦引起橋梁結(jié)構(gòu)的不安全和增強橋梁建筑的美觀。</p><p style="text-indent:25px">鋼橋的結(jié)構(gòu)與受力：1、薄壁結(jié)構(gòu)：為了提高截面效率，鋼橋一般做成薄壁結(jié)構(gòu)，應力計算應該考慮剪力滯、扭轉(zhuǎn)（自由扭轉(zhuǎn)、約束扭轉(zhuǎn)）、翹曲等影響。2、穩(wěn)定（stability）：鋼橋結(jié)構(gòu)剛度小，穩(wěn)定問題突出。作為薄壁結(jié)構(gòu)，為了防止板件的局部失穩(wěn)需要設置加勁肋和限制板件的寬厚比。3、剛度（stiffness）：剛度小，設計中通過限制桿件的長細比（slenderness ratio）、撓度（deflection）和鋼橋的寬跨比保證橋梁的剛度。4、疲勞（fatigue）：構(gòu)件和連接的疲勞強度受材質(zhì)、連接方法與方式、荷載性質(zhì)、應力狀態(tài)、應力幅和應力比的影響。5、連接（connection）：鋼橋構(gòu)件一般由鋼板和型鋼等焊接而成，用高強螺栓(high-strength bolt)或工地焊接拼裝。鋼橋的主要優(yōu)點有受拉、壓、彎、剪均可。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鋼橋深化服務企業(yè),鋼橋"

style="text-indent:25px">鋼橋小知識：鋼橋的大缺點是容易腐蝕，如果鋼橋的設計和養(yǎng)護不當，將嚴重影響鋼橋的耐久性和使用壽命。目前鋼橋采用多的重防腐油漆涂層的防腐壽命只有10年左右，鋼橋在設計使用期內(nèi)需要多次進行除去浮銹、舊漆和重新涂裝。鋼橋所有有可能腐蝕的部位都必須留有足夠的空間和進入通道，如箱形結(jié)構(gòu)橫隔板需要開孔并且滿足人員通過的小尺寸要求，保證結(jié)構(gòu)的可維護性。否則必須采取可靠措施，如將結(jié)構(gòu)做成完全封閉形式阻止鋼材銹蝕產(chǎn)生的條件等，確保鋼橋結(jié)構(gòu)在設計使用期內(nèi)不發(fā)生腐蝕，或者腐蝕控制在預定的程度之內(nèi)。應盡可能避免采用梁高或梁寬很小的箱形截面或不必要的封閉式結(jié)構(gòu)，減小箱內(nèi)焊接和養(yǎng)護的難度。鋼橋深化服務企業(yè)</p><p
