| 中文摘要: |
| 本文提出了一种计算环加肋圆柱壳稳定性的新方法─—复合有限条法。该方法能够在一个复合有限条元中计入若干个横向加肋的影响，井能考虑肋骨的偏心，是一种子结构方法。算例表明，复合有限条法具有很高的求解精度和效率，是一种分析加肋柱壳结构的较理想方法。该方法不仅能够计算环加肋圆柱壳的总体失稳临界载荷，而且可计算其局部失稳临界载荷。 |
| 英文摘要: |
| A new method to analyse the stability of ring-stiffened cylindrical shells is proposed.The method is referred to as the Compound Strip Method(CSM).CSM can take into accountthe effect of transverse stiffeners and consider the influence of the eccentricity of stiffeners.It is a substructure technique. Numerical examples show that CSM possesses very high accu-racy and efficiency.It is an ideal method to analyse the stiffened plate and shell structures.CSM is capable of calculating not only the general but also the local critical buckling loads ofring-stiffened cylindrical shells. |
