摘　　要：分析六种网格形式的单层球面网壳的风振响应,在频域内直接求解网壳风振响应(位移、内力、加速度)的统计值,研究不同网格形式及不同矢跨比对单层球面网壳风振响应的影响.The windinduced vibration responses of six types of singlelayer spherical reticulated shells are analyzed in this paper.Windinduced vibration responses of reticulated shells (displacement,internal force,velocity and acceleration)are calculated in frequency domain.The influence of grid forms and risetospan　ratios on windinduced vibration responses of reticulated shells is also calculated.
