Results of an ongoing inter-laboratory comparative study
of approach flow and wind pressures on low buildings are
presented. The wind tunnel data generated at six wind
engineering laboratories during a pilot project
initiated and coordinated by the National Institute of
Standards and Technology was employed. Variability in
the laboratory wind loading on low buildings was
investigated. The largest variability in the laboratory
wind pressures and in the associated wind-induced
internal loading in structural frames of generic low
buildings was found for suburban wind exposure, for
which an average coefficient of variation of 26.6% was
observed. This variability was primarily attributed to
differences in the approach flows employed in physical
modeling of wind pressures on tested buildings, carried
out by the participating laboratories. The variability
in the approach flows resulted in a large measure from
the differences in the along-wind turbulence intensity
implied by different empirical models, defining the
target wind exposures and used by the laboratories.
