This paper reports the results of wind-tunnel and full-scale measureme
nts of wind pressure on metal edge flashings. The wind-tunnel tests pr
ovide useful information on failure mechanisms of the hashing-cleat sy
stem. The wind pressure data collected at the Texas Tech University Wi
nd Engineering Research Field Laboratory (WERFL) building represent th
e effects of the natural wind. Finite element analyses using pressure
data from the full-scale tests calculate stresses at critical sections
of the edge flashing and pull-out forces on the fasteners. The result
s suggest outward acting fastener pull-out forces, even when the wind
is blowing toward the face of the edge flashing (windward wind).
