摘要
本文的主要目的是建立以刚性模型测压试验为基础的大型体育场主看台弧形悬挑屋盖风振实用计算方法。在初步掌握这类结构的风荷载特性的基础上,本文对振动模态进行了深入的分析,并根据弧形结构的特点,在极坐标下推导了其风致响应的频域计算公式,为今后的进一步研究提供了必要的理论准备。
Based on the rigidity model manometric test, the main purpose of the paper is to establish a utility wind induced vibration calculation method of the large scaled stadium's grandstand arched canopy roofs. After primary understanding the wind load characteristics of these kinds of structures, the vibration modal is analysed in depth in this paper, and the frequency domain calculation formula under polar coordination is deduced according to the characteristics of the arched structures.
