| 摘 要： | 拱形波纹钢屋盖是一种新颖的金属拱形薄壳结构，在我国已经得到了广泛的应用。由于结构的复杂性，目前有关的理论研究尚不够深入，动力研究还很少有人涉及。以18m和30m两种跨度的W666型拱形波纹钢屋盖为研究对象，测试了拱在竖向平面内振动时的频率、振型及阻尼。在所提简化计算模型的基础上，采用有限元方法计算了结构的动力特性，其结果与试验数据符合较好。测试和分析结果为该结构的动力反应研究提供了方便。

| Abstract: | Arched corrugated steel roof is a novel kind of thin-shell structure and is widely used in China. Because of complication, so far there is no deep theoretical study for this kind of structure. Also few references about dynamic research were found. 18m and 30m span W666 arched corrugated steel roofs are taken as the research object and the natural frequencies, vibration modes and damping ratio were measured. The dynamic properties of the structures were analyzed by finite element method based on the simplified calculating model. The analysis results are consistent with the measuremed data very well. The measurement and analysis results can be taken as the reference for the dynamic response research of this kind of structure. |
