(河北省冶金设计研究院 石家庄 050021)[提要] 通过对钢梁截面参数b / t,h0 / tw,h / b 的简化提出焊接工字形钢梁截面设计的直接算法,克服了常用的试算法的缺点,能直接算出经济合理的截面尺寸。
[关键词] 钢梁 工形截面 焊接 截面设计 直接算法 整体稳定 局部稳定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.
