style="text-indent:25px">鋼橋疲勞：由縱肋、橫梁和蓋板三者之間焊接組成的正交異性鋼橋面板因輕質(zhì)、**、施工快的優(yōu)點，已在國內(nèi)外大中跨度的現(xiàn)代公路鋼橋中得到普遍的應用。然而，由于直接承受車輛的局部作用，應力影響線短，～輛車駛過會引起數(shù)次應力循環(huán)，加上焊接節(jié)點的應力集中和難免的焊接缺點，鋼橋面板易于疲勞開裂。鋼橋疲勞是由于日常各種荷重的車輛反復作用而引起的累積損傷過程，因此疲勞驗算所用的荷載應盡可能的與實際相符，這需通過現(xiàn)場交通調(diào)查得到各種典型車輛的荷重和它們出現(xiàn)的相對頻率，即典型車輛荷載頻值譜，并在調(diào)查的基礎(chǔ)上結(jié)合預測分析得到年或日平均交通量的估算。</p><p style="text-indent:25px">鋼橋小知識：為了防止鋼橋的橫向失穩(wěn)和過大的橫向振動，橋梁結(jié)構(gòu)應具有必要的橫向剛度。特別是鐵路鋼橋，往往是橋?qū)捿^窄、活載大、列車的蛇行運動容易產(chǎn)生橫向振動，橫向穩(wěn)定問題較為突出。在特大跨度公路鋼橋中，寬跨比減小，也有可能出現(xiàn)橫向失穩(wěn)，特別是大跨度鋼拱橋，應該從構(gòu)造和結(jié)構(gòu)尺寸兩方面保證結(jié)構(gòu)的橫向穩(wěn)定。通常，跨長超過橋?qū)挼?0倍時，應該驗算橋梁結(jié)構(gòu)的橫向穩(wěn)定。橋跨結(jié)構(gòu)在施工架設(shè)時期也應保證橫向和縱向的傾覆穩(wěn)定性。公路鋼橋規(guī)范規(guī)定，穩(wěn)定系數(shù)應不小于1.3。鋼橋設(shè)計在初期設(shè)計階段就將防腐蝕問題考慮進去。</p><div
