继《在偏心荷载作用下钢吊车梁的静力试验研究》一文,对偏心扭矩和水平力扭矩对吊车梁腹板应力和变形影响作初步探索的基础上,又做了几种不同梁、轨的偏心荷载静力试验(见图1)。本文着重分析腹板附加弯曲应力的性质和分布规律,并探讨了腹板附加弯曲应力的计算方法。关于影响腹板附加弯曲应力的其他因素,将另有专题报告。
Following the article “static test of steel crane beam under eccentric load”, based on the preliminary exploration of the influence of eccentric torque and horizontal torque on the stress and deformation of crane girder web, several different beams and rails Eccentric load static test (see Figure 1). This paper focuses on the analysis of the nature and distribution of additional bending stress in webs and discusses the calculation method of additional bending stress in webs. There will be another special report on other factors that affect the additional bending stress on webs.
