单层球壳结构在简单荷载作用下的动力稳定分析
|
摘要
首先建立单层球壳结构动力稳定判定准则,进而对K8型单层球壳结构在三种简单荷载作用下的动力稳定性进行分析。通过研究同等荷载下不同单层球壳模型的动力稳定性,从而得出其规律。
Judgment criteria is presented for dynamic stability of single layer reticulated shells, which is employed to analyze dynamic stability of k8 single layer reticulated shells under three simple loads. The laws of dynamic stability are obtained using dynamic analysis of different shell models under the same loading.
