style="text-indent:25px">鋼橋結構與受力1、薄壁結構。為了提高截面效率，鋼橋一般做成薄壁結構，應力計算應該考慮剪力滯、扭轉（自由扭轉、約束扭轉）、翹曲等影響。2、穩(wěn)定（stability）鋼橋結構剛度小，穩(wěn)定問題突出。作為薄壁結構，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（slendernessratio）、撓度（deflection）和鋼橋的寬跨比保證橋梁的剛度。4、疲勞（fatigue）構件和連接的疲勞強度受材質、連接方法與方式、荷載性質、應力狀態(tài)、應力幅和應力比的影響。5、連接（connection）鋼橋構件一般由鋼板和型鋼等焊接而成，用**螺栓(high-strengthbolt)或工地焊接拼裝。</p><p style="text-indent:25px">橋梁設計基本原則及要求：橋梁設計必須遵照適用、經(jīng)濟、安全和美觀的基本原則進行，必須考慮下述各項要求。1．使用上的要求。橋梁必須適用。要有足夠的承載和泄洪能力，能保證車輛和行人的安全暢通；既滿足當前的要求，又照顧今后的發(fā)展，既滿足交通運輸本身的需要，也要兼顧其它方面的要求；在通航河道上，應滿足航運的要求；靠近城市、村鎮(zhèn)、鐵路及水利設施的橋梁還應結合有關方面的要求，考慮綜合利用。建成的橋梁要保證使用年限，并便于檢查和維護。2．經(jīng)濟上的要求。橋梁設計應體現(xiàn)經(jīng)濟上的合理性。一L刀設計必須經(jīng)過洋細周密的技術經(jīng)濟比較，使橋梁的總造價和材料等的消耗為較小，在使用期間養(yǎng)護維修費用較省，并且經(jīng)久耐用。另外，橋梁設計還應滿足快速施工的要求，縮短工期不*能降低施丁費用，而且盡早通車在運輸上將帶來很大的經(jīng)濟效益。美觀上的要求。在滿足上述要求的前提下，盡可能使橋梁具有優(yōu)美的建筑外型。</p><div

style="text-indent:25px">鋼橋是一種橋跨結構用鋼材建造的橋梁。1874年美國在密西西比河上建造了世界上一座大型鋼橋——圣路易斯(St.Louis)鋼拱橋，第二次世界大戰(zhàn)以后，鋼橋科學技術在**較好鋼的冶煉，焊接技術的提高，正交異性鋼橋面板和**螺栓的應用，以及結構型式的多樣化等方面，有了很大的發(fā)展，促使大跨度鋼橋的普遍采用。由于鋼材強度高，性能優(yōu)越，表觀密度與容許應力之比值小，故鋼橋跨越能力較大。鋼橋的構件制造較適合工業(yè)化，運輸與安裝均較方便，架設工期較短，破壞后易修復和更換，但鋼材易銹蝕，養(yǎng)護困難。北京好的鋼橋深化設計軟件價格</p><p
