Deck pavement of built - up bridge may be too thick or thin due to complex reasons , among which a most important one is the design 摘要裝配式橋梁建造時會出現(xiàn)橋面鋪裝厚度過薄或過厚的現(xiàn)象,原因很復(fù)雜,但設(shè)計是一個重要原因。
Conventional method of designing built - up bridge can only ensure the deck pavement thickness near the ends of beams , without enough regarding of the middle part 裝配式橋梁的常規(guī)設(shè)計方法一般只能保證支座附近的橋面鋪裝厚度,橋梁的中間部分則無法保證。
A baseline finite element model must be a full three - dimensional model that can reflect the built - up bridge conditions comprehensively and correctly . in addition , it must be a model properly validated by the bridge field tests 斜拉橋基準(zhǔn)有限元模型首先應(yīng)該是能夠全面、正確反映結(jié)構(gòu)真實性態(tài)的完整的計算模型,其次,它還應(yīng)該是經(jīng)現(xiàn)場試驗驗證了的有限元模型。
