考虑空间相关性的高层结构脉动风荷载模拟

he fluctuating characteristics, such as spatial correlation and power spectrum density of fluctuating wind, are considered in this paper to study natural wind speed. The calculation procedure of simulating structural fluctuating wind speed is deduced based on linear filtering method. And then the random fluctuating wind-loads and corresponding characteristics of a tall building are simulated and investigated in detail. The results show that the spatial and temporal correlation of fluctuating wind can be well simulated by the linear filtering method. The simulation accuracy and computational stability can also be ensured effectively. The spatial correlation is Spatial correlation of fluctuating wind is prominent and has influence in a certain extent to fluctuating wind characteristic of neighbor points.
