style="text-indent:25px">鋼橋設(shè)計一般要求和原則：鋼橋在安裝或檢修支座時，常需將梁頂起，故在結(jié)構(gòu)上應(yīng)預(yù)設(shè)可供頂起作用的結(jié)構(gòu)（如在千斤頂支撐處預(yù)設(shè)加勁肋、牛腿或在連續(xù)梁的中間支點(diǎn)處設(shè)置可供頂起用的結(jié)構(gòu)等）?？紤]到頂起時受力的不均勻及其他偶然因素，頂起結(jié)構(gòu)應(yīng)按實有重量超載30％驗算。在布置千斤頂位置時，需要考慮更換支座等必須的操作空間。由于鋼板厚度可能有軋制負(fù)公差，且在長期運(yùn)營過程中會產(chǎn)生銹蝕現(xiàn)象，因此對構(gòu)件應(yīng)規(guī)定鋼板和型鋼的較小厚度。節(jié)點(diǎn)板位于幾根桿件交匯的部位，弦桿與腹桿的內(nèi)力是通過節(jié)點(diǎn)板來傳遞的，因此節(jié)點(diǎn)板應(yīng)力狀態(tài)比較復(fù)雜，既有壓應(yīng)力，也有拉應(yīng)力，還有剪應(yīng)力，應(yīng)力分布也極不均勻。焊接板梁為保證腹板穩(wěn)定和減小殘余應(yīng)力，板厚均不宜過小，故規(guī)定以不小于10mm為宜。對于主梁、行車系或聯(lián)結(jié)系，因考慮可能采用有懸伸翼緣的I形或T形構(gòu)件，從滿足較小寬厚比的要求出發(fā)，規(guī)定以不小于8mm為宜。填板為非受力構(gòu)件，規(guī)定不小于4mm。鋼橋的構(gòu)件較適合用工業(yè)化方法來制造，便于運(yùn)輸，便于無支架施工。好的鋼橋深化設(shè)計軟件公司哪家好</p><p

style="text-indent:25px">鋼結(jié)構(gòu)構(gòu)件一般都在工廠制造、加工，工業(yè)化程度較高，精度高。鋼結(jié)構(gòu)橋梁主要應(yīng)用范圍“”城市立交橋段，尤其是交通要道處，如果采用混凝土橋，必然增加施工周期，對于現(xiàn)場交通不能較好地維護(hù)。大跨徑海、江、河橋梁（長江大橋、杭州灣大橋等），因為大跨徑的要求下，只能考慮鋼結(jié)構(gòu)，如果采用混凝土結(jié)構(gòu)，根本滿足不了大跨徑要求。鋼結(jié)構(gòu)橋梁整體設(shè)計理念：我國橋梁鋼結(jié)構(gòu)的設(shè)計使用年限為100年，與國際標(biāo)準(zhǔn)（BS5400，EUROCODE）基本一致。設(shè)計除對結(jié)構(gòu)、構(gòu)件連接及構(gòu)造細(xì)節(jié)按常規(guī)考慮強(qiáng)度、剛度要求外，尚需對損傷與損傷容限、斷裂與抗斷裂作出評定。橫向抗傾覆是當(dāng)前鋼結(jié)構(gòu)橋梁研究的熱點(diǎn)內(nèi)容。北京正規(guī)鋼橋深化價格</p><p
