| 摘 要： | 拱型波纹钢屋盖结构自重轻,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.利用ANSYS有限元软件中的壳单元Shell63模拟拱型波纹钢屋盖结构,研究了结构的自振频率和振型,并对结构在脉动风荷载作用下的性能进行了随机振动分析.研究成果不仅验证了脉动风荷载对这种结构是一种非常不利的荷载形式,而且给出了这种结构风振系数的建议取值.

| Abstract: | It is generally considered that the seismic response of Arched Corrugated Steel Roof(ACSR) is not the control factor of structure design because of its light weight,but the wind-induced dynamic responses on the structure is significant,Therefore,more attention should paid on it.In this paper,ACSR was modeled by element Shell63 by ANSYS commercial software,and the frequency domain analysis on wind-induced dynamic responses of ACSR was carried out.The conclusion demonstrates that the pulsating wind load is a vary harmful for the structure of ACSR,and the suggested coefficient of wind vibration was given. |
