</p><p style="text-indent:25px">鋼箱梁一般由頂板、底板、腹板、和橫隔板、縱隔板及加勁肋等通過全焊接的方式連接而成。其中頂板為由蓋板和縱向加勁肋構(gòu)成的正交異性橋面板。典型的鋼箱梁各板的厚度可為：蓋板厚度14mm，縱向U形肋厚度6mm，上口寬320mm，下口寬170mm，高260mm，間距620mm；底板厚10mm，縱向U形加勁肋；斜腹板厚14mm，中腹板厚9mm；橫隔板間距4.0m，厚度12mm；梁高2～3.5m。鋼板箱形梁是工程中常采用的結(jié)構(gòu)形式.為研究橫隔板間距對集中荷載作用下簡支鋼箱梁畸變的影響,通過設(shè)置不同數(shù)量橫隔板的簡支鋼箱梁,比較其在集中荷載作用下的畸變效應(yīng)和剛性扭轉(zhuǎn)效應(yīng),得到大畸變效應(yīng)隨橫隔板數(shù)量的變化曲線.在箱梁腹板頂端施加集中荷載,按畸變、剛性扭轉(zhuǎn)、對稱彎曲和偏心荷載四種工況采用荷載分解的方法進行計算.鋼箱主梁的跨度達幾百米及至上千米，一般分為若干梁段制造和安裝。</p><div
