Paper Title:
Characteristics of Wind Loads on Spherical Shells with Large Rise-Span Ratio
  Abstract

Characteristics of wind pressure distributions over the spherical shell with 3/4 rise-span ratio have been investigated based on the data obtained from a wind tunnel experiment. A discussion of the spectral characteristics including shape of wind pressure spectra, reduced frequency corresponding to the peak spectral amplitude, and spectral slope in high frequency range is also made. The results show that the normalized pressure spectra has a broadband peak at a reduced frequency between 0.15 and 0.50, the slope of Sp( f ) in a high frequency range varies from -1.85 to -0.30 and the reduced peak frequency depends on the tapping locations. Though spectral patterns change from place to place, standard normalized spectra associated with various zones of spherical shell could be appropriately classified based on identical spectral characteristics. On this basis, an empirical spectral equation is figured out including three parts which represent the contribution of approach turbulence, turbulence induced by separation on the top of spherical shell and wake turbulence respectively. The accuracy of model is verified by comparison with the measured spectra results.
