摘要
结合两座实桥的布载工况 ,应用空间分析法 (有限元法与有限条法 )和平面杆系分析法 (计入内力增大系数和剪滞效应 )分别计算了控制截面的上、下翼缘最大应力值 ,对比了德国 DIN10 75标准与我国现行 JTJ0 2 3- 85桥规中关于翼缘有效计算宽度的精度 ,所提供的一组数据 ,可供修订规范时的参考。
Applied the space analysis methods (Finite-element method and Finite-strip method) and the plane analysis methods (take into account the force-increase coefficient and shear lag effect of structures), this paper calculated the maximum stresses on the top and bottom flanges of main cross section for two continuous box girders, bearing truck loads respectively, and compared the calculation precision of effective flange width by German Standard DIN 1075 and by National Standard JTJ 023-85. A group data, received by this analysis, may be significance for reference, when our Standard will be revised.
