摘要
根据空间风场模拟技术和结构随机振动理论,运用MATLAB编制了大跨网架屋盖上各点风速模拟程序,结合ANSYS动力分析模块和APDL参数化设计语言的二次开发,对体育中心网架钢屋盖进行了风振响应的时程模拟分析。结果表明,该方法能合理而准确地反映大跨网架屋盖结构在风场作用下的响应,可用于工程设计。
Based on wind field simulation and structures stochastic vibration, MATLAB and the second development of ANSYS were combined to analyze wind-induced vibration response of the gymnasium＇s long-span grid roof. The results show that the method can get the reflection about wind-induced vibration response of the gymnasium＇s roof correctly.
