| 摘 要： | 拱型波纹钢屋盖结构自重轻，地震作用下的动力问题不是结构设计的控制因素，但是在风荷载作用下结构的动力响应较为显著，在设计中应给予足够重视。首先利用ForIran编程工具，模拟结构的风速时程曲线，然后利用ANSYS有限元软件中的瞬态动力学分析模块对这种结构进行动力时程分析，讨论其在脉动风荷载作用下的动力响应，给出了结构风振系数的建议值，且针对风荷载提出了这种结构在设计中应注意的问题。

| Abstract: | It is generally considered that the seismic response of arched corrugated metal roof is not the control factor of structure design because of its light dead weight, but the wind-induced dynamic response on the structure is significant, so more attention must be paid to it. First, the wind simulation of the structure by AR model is carried out. Then, the TRANS method in the ANSYS is used to calculate the dynamic responses in time domain to compare the results with those in frequency domain in order to verify the validity of the two methods. |
