摘要
弹性约束杆之临界力和变形不仅与杆截面特性相关，还取决于约束条件。本文结合起重机设计规范（ＧＢ３８１１－８３），在文献［１］已讨论的两端弹性约束杆基础上，再就一端自由另一端弹性约束的悬臂柱之临界力和挠度影响系数进行分析。
Critical force and deformation of elastic restraint rod not only depend on the rod cross section, but also on the restraint condition. This paper analyzes the critical force and deflection effective coefficient of cantilever column with one end fine and another end restraining elastically. The paper uses crane design standard (GB3811-83) and is based on the result of the rod with Two elastic restraint ends which was discussed on the reference[l].
