This paper is carried out to analyze the buffeting of long-span steel arch bridge in operation and erection stage. The research is mainly focused on the following aspects: Based on the present AR method, the AIC rule is used for fix the rank of the AR model to improve the simulation precision. Take into account that the wind speed spectrum is vary with the height for the long-span steel arch bridge, simulate the fluctuating wind field.

主要工作有以下几个方面：通过对现有的AR法进行改进，采用最小AIC(A-Information Criterion)准则准确识别模型阶数，提高AR法的计算精度，并考虑大跨度钢拱桥风速谱随高度变化的特点，实现了对三维空间脉动风场的有效模拟。
