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 windinduced vibration responses of six types of singlelayer spherical reticulated shells are analyzed in this paper.Windinduced vibration responses of reticulated shells (displacement,internal force,velocity and acceleration)are calculated in frequency domain.The influence of grid forms and risetospan ratios on windinduced vibration responses of reticulated shells is also calculated.
