介绍了钢托盘受压构件交互屈曲研究的第1部分,试验在罗马尼亚蒂米什瓦拉理工大学CEMSIG研究中心进行,该部分对试验方案1和方案2进行了总结。根据欧洲设计规范托盘货架系统结构设计的原则EN15512,对两种不同截面(穿孔和未穿孔)的立柱构件进行了试验,以确定以下试样的极限强度:试样高度与局部屈曲相应,例如,短柱;试样高度与框架柱间距相等,例如,立柱。最后进行了一组专项试验,以观察立柱的畸变屈曲。然而,根据截面大小,节间长度通常大于畸变临界长度。在这种情况下,测试结果与畸变-整体交互作用而不是纯扭曲响应。因此,准备了高度与畸变屈曲相应的附加试样,以及高度与交互式畸变整体屈曲相应的附加试样,分别对它们进行了测试。此外,还进行了材料试验,并测量了几何缺陷。
The first part of the interactive buckling study of steel tray compression members was introduced. The experiment was carried out at the CEMSIG Research Center of Timisoara University of Technology in Romania. This part summarizes the experimental methods 1 and 2. According to EN15512, a guide to the structural design of pallet rack systems in the European Design Code, two column members of different cross-sections (perforated and non-perforated) were tested to determine the ultimate strength of specimens with a height corresponding to local buckling, eg, Short column; sample height equal to the spacing of the frame column, for example, column. Finally, a series of special tests were conducted to observe the distortion of column. However, the internodal length is usually larger than the critical critical length depending on the size of the section. In this case, test results and distortions - the overall interaction rather than the pure distortion response. Therefore, additional specimens corresponding to height and distortion buckling, as well as additional specimens of height corresponding to the overall buckling of the interactive distortion, were prepared and tested separately. In addition, material tests were conducted and geometrical defects were measured.
