style="text-indent:25px">經(jīng)濟是鋼橋結(jié)構(gòu)設(shè)計的保證：一座鋼橋建筑設(shè)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(shè)計也是失敗的。在樂山市大渡河龔嘴電站大橋設(shè)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(shè)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(shè)計中，在滿足結(jié)構(gòu)安全的前提下，應(yīng)盡量地考慮經(jīng)濟。鋼橋設(shè)計不僅要滿足使用階段的受力和工作性能要求，而且應(yīng)分析施工吊裝和調(diào)整支座等受力狀況。上海好的鋼橋繪圖軟件價格</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(yīng)力計算應(yīng)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(shè)置加勁肋和限制板件的寬厚比。3、剛度（stiffness）：剛度小，設(shè)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(yīng)力狀態(tài)、應(yīng)力幅和應(yīng)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。上海好的鋼橋深化設(shè)計軟件公司哪家好</p><p
