摘要:
在《钢吊车梁在集中扭矩作用下腹板附加弯曲应力的试验研究及计算方法》一文中,主要探讨了在集中扭矩作用下,腹板附加弯曲应力的计算问题。计算公式中反映了轨道及翼缘的抗扭刚度、计算板段的几何尺寸等几个主要参数,而实际上影响腹板附加弯曲应力的因素很多,如轨道的抗弯刚度、翼缘的抗弯刚度、轨底宽度、轨道与翼缘接触面的平整紧密程度等。本文仅对影响较大的两个因素即轨道抗弯刚度及轨道与翼缘的接触传力情况对腹板附加弯曲应力的影响作进一步分析。
Abstract:
In the paper "Experimental Investigation and Method of Calculation for Additional Bending Strsses in Web Under Concentrated Torsional Moment and the Steel Crane Girder", only the main parameters, namely the torsional rigidity of rail and flange, physical magnitude, etc. are considered. However there are other parameters which influence the additional bending stresses in web. In this paper, two additional factors, namely the flexural rigidity of rail and the degree of contact between rail and flange, are analysed.
