| 摘 要： | 弦支穹顶结构是一种新型预应力结构体系，综合了单层网壳结构和索穹顶结构各自的优点。以具有实际工程意义的50m跨度凯威特型弦支穹顶结构作为研究对象，讨论了弦支穹顶结构的动力失稳特点；对比分析结构分别在一维、二维和多维地震作用下的动力稳定性，考虑了矢跨比对结构动力稳定性的影响。为弦支穹顶结构的工程应用提供有价值的参考。

| Abstract: | As a new type of structural form, the suspendome structure combines both benefits of the single layer reticulated shell structure and the cable-dome structure. Taking suspendomes with span of 50 m as examples, dynamic stability behavior of some proto-type suspendomes with rise-to-span ratios is discussed, and a comparison analysis on the influence of stability behavior of suspendome under multi-dimensional excitations is carried out. Some valuable conclusions are drawn for practical design. |
