摘要
以郑州大学新校区体育馆钢屋盖为研究对象,采用ANSYS分析程序,建立了钢屋盖空间结构计算模型,利用子空间迭代法计算自振周期和振型,从而得到钢屋盖动力特性,为进一步研究该结构的动力响应打下基础。
The steel roof of the new campus＇ s gym in Zhengzhou University is used as a subject of study, and a computer model of space structure of the steel roof is established by the program ANSYS, as well as the its nature vibration periods and moes are calculated by the subspace iteration method. Therefore, the dynamic properties of the steel roof can be obtained, which provides a foundation for further study of the modal response of the structure.
