[摘要] 首先利用MATLAB编程工具采用线性滤波法，模拟了不同矢跨比的开敞式拱形波纹钢屋盖结构的风速时程曲线，然后利用ANSYS有限元分析软件中的瞬态动力学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，并将时域分析与之前频域分析的结果进行对比，最后总结此类屋盖结构的风振规律并给出计算风振系数的公式，以供设计施工人员参考使用。

Abstract: Based on linear filtering, time history curves of fluctuating wind velocities of different rise-to span ratio open-type arched corrugated steel roof were simulated in MATLAB, and the rIRANS method in ANSYS was used to calculate the dynamic responses in time domain. The results were compared with those in frequency domain in order to verify the validity of the two methods. Vibration coefficient formula of such structure was given for the designer and constructer reference.
Keywords: open-type; arched corrugated steel roof( acsr); wind-induced dynamic response; time domain analysis
