起重机小车或电葫芦在箱形梁或轧制型钢的下翼缘上运行时产生了如图1所示的局部弯曲变形,图1中R为小车轮压。很多作者对此进行过理论及实验研究,并得出了各不相同的结果。根据Becker及Mendel的实验数据以及本文作者对箱形梁下翼缘进行测量的结果推荐按下式进行计算:
Crane trolley or electric hoist in the box beam or rolling under the flange on the flange produced when the local bending deformation shown in Figure 1, R in Figure 1 for the car wheel pressure. Many authors have conducted theoretical and experimental research on this and have come up with different results. Based on the experimental data of Becker and Mendel and the results of the authors’ measurements of the lower flange of box girder, the following formula is recommended:
