APPLICATION INVESTIGATION OF PREDICTING WIND LOADS ON LARGE-SPAN ROOF BY KRIGING-POD METHOD

  • 摘要: 结合POD (Proper Orthogonal Decomposition)技术与Kriging法,提出用于空间数据插值的POD-Kriging方法;基于大跨屋盖结构表面风压的数据,实现了对风压的空间重构与预测。预测的平均风压系数、脉动风压系数、脉动风压的时域与频域特性与风洞实验结果吻合良好。表明该文提出的预测方法在大跨结构表面风压的预测是可行的。

     

    Abstract: The POD-Kriging method is proposed, based on the combinations of POD (Proper Orthogonal Decomposition) technique and Kriging method, for the interpolations of spatial data. And the wind pressures are predicted and reconstructed based on wind tunnel test results of a large-span roof structure. The predicted results, such as mean and RMS wind pressure coefficients and fluctuating wind load characteristics in time and frequency domain, are well agree with that obtained from wind tunnel tests. The proposed method is feasible to predicting wind loads on large-span roof structure.
