Amodel of a high-rise office building at 1/550 scale is tested in a wind tunnel to estimate the pressures and forces on the full-scale structure. the wind-tunnel air speed is 20 m/s at 20°c and atmospheric pressure, and the full-scale structure is expected to withstand winds of 200 km/h (10°c). if the extreme values of the pressure coefficient are found to be 1.0, –2.7, and –0.8 on the windward wall, side wall, and leeward wall of the model, respectively, what corresponding pressures could be expected to act on the prototype? if the lateral wind force (wind force on building normal to wind direction) was measured as 20 n in the model, what lateral force might be expected in the prototype in the 200 km/h wind?
