style="text-indent:25px">鋼板箱形梁是工程中常采用的結(jié)構(gòu)形式，例如大型吊車(chē)梁、橋梁的主梁等。采用鋼板箱梁是由于它具有很大的抗扭剛度，因而在偏心荷載作用下，箱梁的整體受力情況較之其他型式的梁更為有利。在計(jì)算偏心荷載作用下箱梁的內(nèi)力與變形時(shí)，即將荷載作用分解成對(duì)稱(chēng)荷載與反對(duì)稱(chēng)荷載之和。箱梁在對(duì)稱(chēng)荷載作用下將引起對(duì)稱(chēng)彎曲,但不產(chǎn)生任何扭轉(zhuǎn)現(xiàn)象;而在反對(duì)稱(chēng)荷載作用下，將引起扭轉(zhuǎn)(自由扭轉(zhuǎn)和約束扭轉(zhuǎn))與畸變。對(duì)稱(chēng)彎曲使箱梁截面上產(chǎn)生縱向彎曲正應(yīng)力Br;約束扭轉(zhuǎn)將使箱梁截面上產(chǎn)生縱向翹曲正應(yīng)力Br;而畸變則使箱梁截面上產(chǎn)生縱向畸變正應(yīng)力Paw。鋼箱梁材料有鋼材和預(yù)應(yīng)力鋼筋混凝土兩種。</p><div
