Fluctuating wind pressure measured with tubing system

Abstract Methods to measure fluctuating pressure passing through PCV tube has been developed. This research concerns with a method using PCV tube and a method averaging pressures on many points by using multi-tubes system. It was confirmed that the FFT digital filter method eliminated the distortion caused by PCV tube and that the multi-tubes system possessed the characteristic of averaging pressures on many points. The tube system was applied to field measurement of dome and wind tunnel test of rectangular prism. Useful result for pressure was obtained from the field measurement and a response analysis of building was conducted as the wind force was the averaged pressure measured with multi-tubes system.
