摘要
箱形圆环曲梁在大型高炉和现代超高烟囱内钢筒的吊装等工程中得到广泛应用 针对这类闭合圆环曲梁 ,采用薄壁曲梁解析法 ,计算了其在垂直均布荷载和扭矩作用下的内力 与文〔1〕比较 ,所计算的双力矩Bω 较小 ,且与试验结果更为接近 因此文中理论计算更可靠 。
The closed ring-shape beam with single box is extensively applied in the engineering, such as large blast furnaces,elevating an inner steel tube of a chimney etc.The analysis method in accordance to this ring-shape curve beam with the thin walled box section is adopted to compute its internal forces under the vertical uniform distributed load and torsion.The calculating that for the bimoment B ω is much less than the that of the literature 〔1〕,and the normal stress approaches further to the test values.Therefore the theoretic result can be provided for designers' reference.
