ESDU 89050:2012

ESDU 89050 gives graphical data for peak and area-averaged mean
forces on panels in infinite walls, panels near the free end of a
semi-infinite wall, panels near a right-angled corner, finite
length walls, elevated panels and pairs of parallel walls. Peak
design loads are obtained by using the peak forces in conjunction
with the design hourly-mean wind speed. The data were derived from
wind-tunnel test results extracted from the literature in which the
typical variation of wind speed and turbulence with height was
modelled. The correlation yielded a mean force that depended on the
flow angle to the wall and the terrain upwind, and a peak
fluctuating component that depended on the turbulence and the panel
size in relation to the mean wind speed. Corresponding mean and
peak overturning moments are estimated from the centre of pressure
position data given for each configuration. A step-by-step worked
example illustrates the use of the correlation to estimate the
forces on a typical wall. The basis of the analysis of the
experimental data is explained.
