摘要
针对多维AR模型同时求解回归系数矩阵所有元素的一些不足之处 ,本文提出了混合回归模型 ,实例分析表明 ,混合回归模型对脉动风的仿真是有效的 ,用于高层建筑风响应时域分析 。
As multi_dimensional AR model has some drawbacks in the procedure of solving all the elements of the regressive matrixes,the hybrid regressive model is proposed in the paper.Numerical examples show that hybrid regressive model is effective to the simulation of pulsating wind.The results are highly satisfactory when the method is introduced into the time_domain analysis of tall building's response to wind action.
