style="text-indent:25px">鋼橋冬季施工注意事項(xiàng)：1、鋼管構(gòu)件正負(fù)溫制作負(fù)溫安裝時(shí)，應(yīng)根據(jù)環(huán)境溫度的差異考慮構(gòu)件會(huì)出現(xiàn)收縮量，并在鋼結(jié)構(gòu)施工中將偏差進(jìn)行調(diào)整。2、焊條烘焙：焊條往往會(huì)因潮濕而使工藝性能變壞，造成電弧不穩(wěn)、飛濺增大，并容易產(chǎn)生氣孔、裂紋等缺陷。因此，焊條使用前必須采取烘干處理。一般酸性焊條：結(jié)422（E4303）、結(jié)502（E5003）的烘干溫度為 150-200℃，時(shí)間1小時(shí)；烘干后放在保溫箱內(nèi)，隨用隨取。焊條外露不得超過2小時(shí)，超過2小時(shí)重新烘焙，焊條烘焙次數(shù)不超過3次。焊接時(shí)間盡量選擇在白天作業(yè)，上午9點(diǎn)至下午4點(diǎn)之間進(jìn)行二級(jí)焊縫的焊接工作。廣州好的鋼橋深化企業(yè)在通航河道上，應(yīng)滿足航運(yùn)的要求。</p><div

style="text-indent:25px">鋼橋設(shè)計(jì)一般要求和原則：鋼橋的較大缺點(diǎn)是容易腐蝕，如果鋼橋的設(shè)計(jì)和養(yǎng)護(hù)不當(dāng)，將嚴(yán)重影響鋼橋的耐久性和使用壽命。目前鋼橋采用較多的重防腐油漆涂層的防腐壽命只有10年左右，鋼橋在設(shè)計(jì)使用期內(nèi)需要多次進(jìn)行除去浮銹、舊漆和重新涂裝。鋼橋所有有可能腐蝕的部位都必須留有足夠的空間和進(jìn)入通道，如箱形結(jié)構(gòu)橫隔板需要開孔并且滿足人員通過的較小尺寸要求，保證結(jié)構(gòu)的可維護(hù)性。否則必須采取可靠措施，如將結(jié)構(gòu)做成完全封閉形式阻止鋼材銹蝕產(chǎn)生的條件等，確保鋼橋結(jié)構(gòu)在設(shè)計(jì)使用期內(nèi)不發(fā)生腐蝕，或者腐蝕控制在預(yù)定的程度之內(nèi)。應(yīng)盡可能避免采用梁高或梁寬很小的箱形截面或不必要的封閉式結(jié)構(gòu)，減小箱內(nèi)焊接和養(yǎng)護(hù)的難度。</p><p style="text-indent:25px">鋼橋結(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(jì)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(jì)中通過限制桿件的長(zhǎng)細(xì)比（slendernessratio）、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(qiáng)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**螺栓(high-strengthbolt)或工地焊接拼裝。韌性、延性好，可提高抗震性能。</p><div

style="text-indent:25px">鋼橋發(fā)展的重要前提和淺見：設(shè)計(jì)大師邵長(zhǎng)宇指出“橋梁技術(shù)的發(fā)展都離不開材料，但就鋼橋發(fā)展來說，國內(nèi)橋梁用鋼的發(fā)展還有待突破……”。那就是鋼梁的材質(zhì)應(yīng)具有**度、高堅(jiān)韌性、高淬透性、低碳且塑性好并具有高性價(jià)比的環(huán)保材料的特點(diǎn)，一般稱之為高性能鋼（HPS）,如今，我國鋼材產(chǎn)量和質(zhì)量比過去提高很多，但在材料的品種、規(guī)格和性能的多用途上與國外還有較大的差距，因而在一定程度上成了影響著橋梁結(jié)構(gòu)的設(shè)計(jì)和施工工藝的瓶頸。所以橋梁的質(zhì)量、耐久性和跨度的大小與鋼材的創(chuàng)新是密切相關(guān)的。鋼橋構(gòu)件的工廠加工需要經(jīng)過材料預(yù)處理。鋼橋深化設(shè)計(jì)服務(wù)企業(yè)</p><p

style="text-indent:25px">現(xiàn)在，國內(nèi)的結(jié)構(gòu)設(shè)計(jì)過程中，有這樣的傾向：設(shè)計(jì)中考慮強(qiáng)度多而考慮耐久性少；重視強(qiáng)度極限狀態(tài)而不重視使用極限狀態(tài)，而結(jié)構(gòu)在整個(gè)生命周期中重要的卻恰恰是使用時(shí)的性能表現(xiàn)；重視結(jié)構(gòu)的建造而不重視結(jié)構(gòu)的維護(hù)。實(shí)際上，目前的橋梁設(shè)計(jì)中，對(duì)于耐久性更多的只是作為一種概念受到關(guān)注，既沒有明確提出使用年限的要求，也沒有進(jìn)行專門的耐久性設(shè)計(jì)（從材料、結(jié)構(gòu)措施及設(shè)計(jì)程序上上保證耐久性，并明確聲明在何種維護(hù)和使用條件下，橋梁具有哪種程度的耐久性）。這些傾向在一定程度上導(dǎo)致了當(dāng)前工程事件頻發(fā)、結(jié)構(gòu)使用性能差、使用壽命短的不良后果；也與國際結(jié)構(gòu)工程界日益重視耐久性、安全性、適用性的趨勢(shì)相違背；也不符合結(jié)構(gòu)動(dòng)態(tài)和綜合經(jīng)濟(jì)性（考慮結(jié)構(gòu)建設(shè)、使用、維護(hù)等整個(gè)周期的費(fèi)用）的要求。廣州好的鋼橋深化企業(yè)</p><p
