style="text-indent:25px">鋼橋設計的一般要求和原則：必須有足夠的整體剛度、具有必要的橫向剛度、滿足使用階段的受力和工作性能要求，在施工過程中滿足應力和變形的要求、防腐、疲勞設計、不應有未栓合或未焊合的接觸部分、應盡可能減少構件和零件的種類，鋼結構的構件計盡可能標準化，使同型構件能互換、鋼橋在安裝或檢修支座時在結構上應預設可供頂起用的結構?鋼橋的設計方法：容許應力設計法、半概率極限狀態(tài)設計法。結構內力計算原則。結構構件的內力按彈性受力階段確定。變形按構件毛截面計算，不考慮釘（栓）孔削弱的影響。為簡化計算，可將橋跨結構劃分為若干個平面系統(tǒng)計算，但應考慮各個平面系統(tǒng)的共同作用和相互影響。平面計算方法中，可以采用荷載橫向分布系數考慮橋梁結構空間作用的影響。</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*要細心選材，還需要經常檢查和維修，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較晚，但自出現以來不到200年時間就已經被普遍建設，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。鋼橋的優(yōu)點是鋼材的抗拉、抗壓、抗剪強度相對來說較高。</p><div

style="text-indent:25px">鋼橋互動式設計體系制的建立和維護：鋼橋設計決不是一項**的設計工作，其與路線、防護、地質、區(qū)域規(guī)劃等多方面緊密相關。因此作為總體設計的一部分，其與相關方面設計的互動尤為重要。在項目操作過程中，某一項工作的滯后必然會影響到其它工作。在仔細分析一下設計產品，不乏一些節(jié)點上的失控和自相矛盾的現象存在。當然，在設計流程中有很多制度和方法進行信息傳遞，但這種傳遞缺少互動式的設計體系去修復設計失誤、去強化設計部門之間的溝通。鋼橋的設計必須選用有足夠韌性的鋼材，盡可能避免應力集中和容易出現疲勞的構造細節(jié)、連接構造與方法。上海正規(guī)鋼橋繪圖軟件哪家好</p><p

style="text-indent:25px">鋼橋小知識：為了防止鋼橋的橫向失穩(wěn)和過大的橫向振動，橋梁結構應具有必要的橫向剛度。特別是鐵路鋼橋，往往是橋寬較窄、活載大、列車的蛇行運動容易產生橫向振動，橫向穩(wěn)定問題較為突出。在特大跨度公路鋼橋中，寬跨比減小，也有可能出現橫向失穩(wěn)，特別是大跨度鋼拱橋，應該從構造和結構尺寸兩方面保證結構的橫向穩(wěn)定。通常，跨長超過橋寬的20倍時，應該驗算橋梁結構的橫向穩(wěn)定。橋跨結構在施工架設時期也應保證橫向和縱向的傾覆穩(wěn)定性。公路鋼橋規(guī)范規(guī)定，穩(wěn)定系數應不小于1.3。上海正規(guī)鋼橋深化設計下載</p><p
