ratio of rigidity

This paper discusses the allowed width-to-thickness ratio of the sub-panels and the rigidity requirement of the stiffeners used in stiffened composite stub columns.

针对该新型方钢管混凝土轴压短柱，探讨子板件最大宽厚比及加劲肋的最小刚度确定方法。

The analytical results show that, as the transverse rigidity decreases, the area of compressive region increases and the longitudinal effective rigidity ratio decreases.

结果表明，随横向刚度减小，截面受压区面积增大，隧道纵向等效刚度有效率减小；

Tension bar, however, as one of the main parts of port crane, are characterized with big slender ratio and low rigidity, which can easily cause Vortex-vibration.

拉杆是港口起重机重要组成构件，具有细长比大、刚度小等特点，很容易发生涡激振动，而剧烈的振动能够引起拉杆的疲劳开裂，造成安全事故。
