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(duì)于現(xiàn)場(chǎng)交通不能較好地維護(hù)。大跨徑海、江、河橋梁（長(zhǎng)江大橋、杭州灣大橋等），因?yàn)榇罂鐝降囊笙?，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(jì)理念：我國(guó)橋梁鋼結(jié)構(gòu)的設(shè)計(jì)使用年限為100年，與國(guó)際標(biāo)準(zhǔn)（BS5400，EUROCODE）基本一致。設(shè)計(jì)除對(duì)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(duì)損傷與損傷容限、斷裂與抗斷裂作出評(píng)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。鋼橋一般采用工廠焊接構(gòu)件，工地現(xiàn)場(chǎng)拼裝（高強(qiáng)螺栓連接或工地焊接）。</p><div
