摘要:
在国內外部曾发现厂房中,有相当数量承受重级工作制吊车的钢吊车梁使用时间不长,在上翼缘焊缝及其附近腹板处即出现纵向裂缝以至丧失承载能力。这说明现行设计规范对承受重级工作制吊车的钢吊车梁的设计规定还未能全面反映其实际工作状态。本文正是研究这个问题的一个方面。通过偏轨静力试验探索了以下几个问题:1.偏心扭矩对吊车梁腹板应力及变形的影响;2.改变横向加劲肋间距对吊车梁附加弯曲应力的影响;3.水平力对吊车梁的应力及变形的影响;4.吊车轨道对局部荷载的分布作用;5.不同制动结构对吊车梁应力、变形的影响及制动结构的工作情况。对于所探索问题的有关理论分析,另有专题报告。
Abstract:
In our country and abroad it has been observed that many heavy-duty steel crane runway girders develop longitudinal cracks after a few years of service and eventually fail in their carrying capacities. These cracks happen in the welding connecting the web and top flange and in the web in the vicinity of the juncture. These facts indicate that the provisions in the present design specification for crane runway girders are still inadegnate for such heavy-duty crane girders. As a part ot our research program, a series of tests are performed on the steel crane runway girder prototypes under eccentric crane rail loadings, in order to investigate the following problems: 1. Influences of torsional moment due to eccentric transverse loadings at the top flange upon the web stresses and deformations of the girders; 2. Influences on the additional local bending stresses of the web due to changes in stiffener spacings; 3. stresses and deformations of the girders under horizontal loading acting on the top flange; 4. The distributing behavior of crane rails under local concentrated loadings; 5. Influeuces of various kinds of brake-resisting framework on the state of stresses and deformations of the girder as well as the actual behavior of the framework. Theoretical analysis of these problems will be given in separate reports.
