(河北省冶金設(shè)計(jì)研究院 石家莊 050021)[提要] 通過對(duì)鋼梁截面參數(shù)b / t,h0 / tw,h / b 的簡(jiǎn)化提出焊接工字形鋼梁截面設(shè)計(jì)的直接算法,克服了常用的試算法的缺點(diǎn),能直接算出經(jīng)濟(jì)合理的截面尺寸。
[關(guān)鍵詞] 鋼梁 工形截面 焊接 截面設(shè)計(jì) 直接算法 整體穩(wěn)定 局部穩(wěn)定According to the simplification of the section parameters such as b / t,h0 / tw,h / b, a direct calculating method for section design of I-shaped welded plate girder is presented. Different from the trial method, it can give reasonable and economic section directly.
Keywords: I-shaped steel girder; welded plate girder; section design; direct calculating method; stability
