WIND SCREEN SUBDUES GALE FORCE WINDS ON A MOUNTAIN BRIDGE

STUDY IS CONDUCTED TO DETERMINE THE FEASIBILITY OF EMPLOYING WIND SCREENS AS A MEANS OF PREVENTING VEHICLE ACCIDENTS CAUSED BY HIGH VELOCITY CROSSWINDS. AN EXPERIMENTAL WIND SCREEN WAS INSTALLED ON A MOUNTAIN BRIDGE WHERE TRUCK TRAILERS HAD BEEN OVERTURNED BY SPORADIC GALE FORCE SIDE WINDS. THE 10-FOOT HIGH SCREEN WAS MADE OF 9 GAUGE GALVANIZED STEEL CHAIN LINK MESH FENCING WITH ALL OF THE APERTURES FILLED WITH VERTICALLY PLACED CRIMPED ALUMINUM SLATS. THE SPACES BETWEEN THE SLATS RESULTED IN A POROSITY OF 20 PERCENT. THE SCREEN HAS BEEN COMPLETELY SUCCESSFUL IN PREVENTING EITHER THE OVERTURNING OF VEHICLES OR LOSS OF DRIVER CONTROL DURING A TWO YEAR TEST PERIOD. THE REPORT SUGGESTS OTHER TYPES OF LOCATIONS THAT MAY BENEFIT FROM WIND PROTECTION AND OFFERS BASIC DESIGN CONSIDERATIONS. /AUTHOR/
