Abstract
This report is concerned with a study to find the optimum configuration for a full-scale test rig to test the capability of roof systems to withstand damage by high winds. The requirements such a rig should satisfy are discussed. A variety of configurations were tested at reduced scale, using a specially designed apparatus. Open-jet and enclosed-jet configurations were examined. An open-jet configuration is identified as the optimum. A rig that would satisfy the ideal requirements would be very large, would require a great deal of power (about 65,000 horsepower) and would be very costly. Some compromise on pressure pattern size and maximum attainable wind speed probably will be necessary.
