style="text-indent:25px">鋼橋的結構與受力：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（slenderness ratio）、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(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。</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(chǎn)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(xiàn)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(shù)應不小于1.3。南京三橋、蘇通大橋、昂船洲大橋的建造，表明在大跨徑鋼橋的優(yōu)勢越來越明顯。</p><div

style="text-indent:25px">近年來，中國鋼結構橋梁發(fā)展取得了驕人的成績，南京三橋、蘇通大橋、昂船洲大橋的建造，表明在大跨徑橋梁上鋼結構的優(yōu)勢越來越明顯。橋梁是為滿足交通功能的建筑物，現(xiàn)代橋梁鋼結構由結構鋼加上單元經(jīng)焊（栓）連接組成為復雜的受力系統(tǒng)，有明確的承載安全和服役耐久性要求。鋼結構橋跨度較大，如果再加上橋面寬于鋼梁，活載不是優(yōu)，弄不好橫梁外側支座受力增大，而內(nèi)側支座出現(xiàn)不受力，這樣橫梁受力極其不均勻，發(fā)生梁體的傾覆。在設計過程中，通過合理的計算，來設計橫梁的偏心受力情況，這樣既可滿足橋梁的荷載要求，也能使得橋體均勻受力。在橫梁處采取灌砂措施，并在滿足規(guī)范的條件下，增加多車道時的橋梁整體穩(wěn)定度。鋼橋的優(yōu)點是抗震性能好。廣州正規(guī)鋼橋設計公司哪家好</p><p

style="text-indent:25px">經(jīng)濟是鋼橋結構設計的保證：一座鋼橋建筑設計的再如何漂亮，若它的造價比看上去一般化的橋梁高出許多，這座漂亮的橋梁設計也是失敗的。在樂山市大渡河龔嘴電站大橋設計中，定下采用中承式拱橋后，拱圈是用鋼筋砼呢，還是鋼管砼？經(jīng)過比選，我們設計組采用了變截面鋼筋砼拱圈。因為本橋地處偏遠大山之中的大渡河上，當?shù)氐纳?、石料比較豐富，可就地取材，而鋼管拱不僅昂貴，且鋼管運距也相當遠。故在橋梁設計中，在滿足結構安全的前提下，應盡量地考慮經(jīng)濟。好的鋼橋設計服務公司</p><p
