THE SILSOE STRUCTURES BUILDING - COMPARISON BETWEEN FULL-SCALE AND WIND-TUNNEL DATA

Full-scale wind profile and surface pressure measurements made at Sils oe are compared with a series of 1:100 scale experiments conducted in the University of Western Ontario's Boundary Layer wind-tunnel No. 1. The surface pressure comparison was limited to wind directions normal and parallel to the building ridge for a mid-building-length set of pr essure tappings. The pressure coefficients from standard wind-tunnel t ests were referenced to pressures measured above the model-scale bound ary layer. The problems in correcting these to ridge height references are discussed. A time history experiment succeeded in over-coming the se problems with the simultaneous recording of ridge-height velocity a nd a local reference static pressure just upwind of the 1:100 scale mo del. Recommendations for future model and full-scale experimentation a re made.
