A DIGITAL SYSTEM FOR THE MEASUREMENT OF WIND EFFECTS ON LARGE STRUCTURES

Abstract This paper describes an instrumentation system developed specifically for the measurement of wind effects on large structures. The design of the system was based entirely on digital techniques to overcome some of the problems associated with full-scale measurements. An inductive phase difference technique was used to extend the digital concept to the pressure transducer level. Two of these systems are currently employed in measurements involving an aircraft hangar and a power station chimney. The advantages and also the disadvantages of the approach approach are discussed.
