% ，但比環(huán)氧瀝青和澆注式瀝青為低。然而，環(huán)氧瀝青因強(qiáng)度高，鋪裝層因此可以減薄，減輕了自重，又有利于降低造價(jià)；澆注式瀝青鋪裝層厚度也較薄，或與普通瀝青鋪裝復(fù)合使用。如何防止鋼橋的腐蝕，延長(zhǎng)大橋的使用壽命，是橋梁建設(shè)中的重要任務(wù)。北京好的鋼橋深化服務(wù)</p><div

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(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(wèn)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(guò)限制桿件的長(zhǎng)細(xì)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(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-strength bolt)或工地焊接拼裝。鋼橋的防腐：對(duì)于漆膜的綜合耐久性能，還必須考慮到施工條件、維護(hù)管理和經(jīng)濟(jì)等因素。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="北京好的鋼橋深化服務(wù),鋼橋"
