| 摘 要： | 初始几何缺陷对板片结构体系稳定性的影响是板片结构计算和设计中的一个关键问题。提出一种考虑初始几何缺陷的改进随机缺陷法 ,它弥补了一般随机缺陷法人工计算量大的缺点 ,也回答了设计临界荷载和一致缺陷法得到的临界荷载的可靠性问题。实例为一试验模型 ,通过理想模型、一致缺陷法、改进随机缺陷法以及试验结果的对比 ,得出一些对板片结构体系设计和研究有益的结论。

| Abstract: | The effect of initial geometrical imperfections on the stability of sheet space structure is a key to its design and calculation.Advanced stochastic imperfections method is put forward,which does not require a large amount of manual computations and by which the reliability of design critical load and critical load with consistent mode imperfections method can be evaluated.The results of perfect model,consistent mode imperfections method,advanced stochastic imperfections method and experiment are compared,by which some conclusions that are useful for engineering design and study of space sheet structure are obtained. |
