【摘要】 有效的模拟脉动风速时程是进行桥梁风致振动分析的前提。文章采用线性滤波法,建立了脉动风速时程的AR模型,并结合AIC准则有效确定模型阶数,编辑出脉动风速时程模拟程序。通过具体工程的算例分析,验证了该脉动风速时程模拟的可行性与有效性。更多还原

【Abstract】 Effective simulate impulse wind speed time interval is a prerequisite to analyze the wind-induced vibration of bridge structures.Using the linear filter meth-od,the article builds an AR model with AIC rule to calculate the model order and edit a simulation program.Through the analysis on some particular constructions,the feasibility and efficiency of this simulation model is verified.更多还原
