WIND LOADS ON FREESTANDING WALLS IN TURBULENT BOUNDARY-LAYERS

Pressure measurements on walls immersed in turbulent boundary layer fl ow from two different wind tunnel facilities are presented and compare d. A variety of wall configurations, wind directions and shielding arr angements were studied. Some of this data has been incorporated into c odes of practice for the design of free-standing walls. Differences in the most fundamental case, that of a wall completely spanning the win d tunnel, are attributed to differences between the two wind tunnel fl ow simulations over the height of the wall.
