Abstract: This paper put forward for the first time an analysis of the dynamic property in curved plate arch bridges with curved thick shell elements. The performance of the curved thick shell, elements has been compared with the results obtained from the 3D-solid element analysis, and the experimental results. It shows that the curved thick shell element analysis of curved plate arch bridges is quite valid. The dynamic property of the curved plate arch bridges may be analyzed with the IBM personal computer.

摘要： 本文首次应用曲厚壳单元分析弯板拱的动力特性,通过与三维实体单元的分析结果及试验实测值进行比较,说明用曲厚壳元分析弯板拱的动力特性是切实可行的,完全可以代替三维实体单元的分析方法,而且用微机就可解决问题。
