    摘要: This research intends to investigate the cross spectrum characteristics of wind pressure
    fluctuations on the surface along the meridian of domed roofs under turbulent wind flows.
    Wind pressure experiments of domed roofs are conducted considering two roof curvatures
    and three heights of side walls. From the experimental results, various distribution types of
    co-coherences are examined and the traditional exponential decaying form is shown
    insufficient to approximate the general characteristics of co-coherences. By combining the
    proposed models by Uematsu et al [1] and Kanda et al [2] and also a phase shift parameter
    included, the approximation model is then improved to represent the observed coherences
    generally.
