摘　　要：以一实际工程为背景,采用结构最大Z向位移为特征变量,研究了大跨度非规则折板网壳结构在三向地震作用下的动力稳定性能,并考查了初始缺陷、支座形式和屋面支承方式等不同参数变化对单层折板网壳结构动力稳定性能的影响,得出了对该类结构动力稳定性分析设计的有益结论。The folded plate latticed shell structure is developed in recent years as a new type of hybridization spatial grid structure.The dynamic stability about a large-span irregular single-layer folded plate latticed shell structure under the three dimensional earthquakes is discussed in this paper.The influences of the initial geometrical imperfections,the support condition and the roofing bearing form to the dynamic stability and the failure mode of this structure are studied.

关 键 词：折板网壳结构 动力稳定分析 三向地震作用
