摘要
根据网壳结构的动力稳定判别准则,分析了单层鞍型网壳在Pasadena波(取不同时间压缩比)作用下的稳定性能,并将其动力稳定临界荷载与静力临界荷载相对比,得出了一些重要结论。
According to the criterion of Liapunov's stability of reticulated structures,the dynamic stability of single layer latticed saddle shells under Pasadena wave(similarity ratio of time is 1/10 and 1/4)is studied in the paper.Finally,some important conclusions are obtained.
