style="text-indent:25px">鋼橋與鋼混凝土橋的不同之處：雖然鋼橋的強(qiáng)度大，但它抗腐蝕性較弱，所以不僅要細(xì)心選材，還需要經(jīng)常檢查和維修，費(fèi)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(jì)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(shí)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(cuò)選擇。假如需要架建跨度較大的橋梁，則選擇鋼橋更合適。橋的設(shè)計(jì)方法：容許應(yīng)力設(shè)計(jì)法、半概率極限狀態(tài)設(shè)計(jì)法。上海鋼橋設(shè)計(jì)深化價(jià)格</p><p

style="text-indent:25px">鋼橋疲勞：由縱肋、橫梁和蓋板三者之間焊接組成的正交異性鋼橋面板因輕質(zhì)、**、施工快的優(yōu)點(diǎn)，已在國內(nèi)外大中跨度的現(xiàn)代公路鋼橋中得到普遍的應(yīng)用。然而，由于直接承受車輛的局部作用，應(yīng)力影響線短，～輛車駛過會引起數(shù)次應(yīng)力循環(huán)，加上焊接節(jié)點(diǎn)的應(yīng)力集中和難免的焊接缺點(diǎn)，鋼橋面板易于疲勞開裂。鋼橋疲勞是由于日常各種荷重的車輛反復(fù)作用而引起的累積損傷過程，因此疲勞驗(yàn)算所用的荷載應(yīng)盡可能的與實(shí)際相符，這需通過現(xiàn)場交通調(diào)查得到各種典型車輛的荷重和它們出現(xiàn)的相對頻率，即典型車輛荷載頻值譜，并在調(diào)查的基礎(chǔ)上結(jié)合預(yù)測分析得到年或日平均交通量的估算。上海鋼橋設(shè)計(jì)深化哪家好</p><p
