| 摘 要： | 通过对比中美钢结构设计规范和相关技术规程中对高强等边角钢轴压构件稳定承载力计算的规定,认为各规范对于两端理想铰接构件的规定是合理的,但实际构件两端连接的约束往往强于铰接,由此带来的承载力提升较为可观,可以加以利用。文章还以试验统计结果为依据,提出了通过采用合适的计算长度系数来利用这种承载力提升的方法。

| Abstract: | By means of comparing the stipulations for the calculation of bearing capacity of axially loaded compression members of high strength equal angle steel which are specified in both design specifications for steel structure and related technical codes published in China and United States,it is concluded that in these specifications and codes the stipulations for ideal two-end articulated elements are reasonable.However,the restraint for two-end connection of actual struts is always stronger than hinged connec... |
