| 摘 要： | 考虑不同矢跨比、荷载、跨度和支座刚度等多种因素的影响,对单层球面网壳在地震作用下的反应进行了较全面的研究,给出了其随各参数变化的规律,得出了在单层球面网壳抗震设计中起控制作用的是水平地震作用而不是竖向地震作用等有益的结论.此外本文还给出了由于阻尼比不同而需对引用现行抗震规范反应谱分析的网壳地震作用进行修正的建议. |
| 关 键 词： | 单层球面网壳 水平地震作用 动力反应特征 |

| Abstract: | A thorough investigation and study on the influence of some parameters, such as the ratio of height to span, loads, span and the stiffness of supports, on dynamic characteristics and seismic response of single layer latticed domes were made. Some useful conclusions about the seismic performance were obtained, in which the most important concept is that the horizontal seismic response of latticed domes is much larger than the vertical one. In addition, the adjustment factor of seismic action due to different damping ratios for latticed domes was given. |
| Keywords: | single layer latticed dome horizontal seismic response seismic characteristics |
