Development of a high-noise Measurement Instrument in Civil Building Dynamics

Complex buildings or tall buildings built in an earthquake-prone area must be subject to continuous measuring of dynamic building parameters. The continuous monitoring of the building condition helps in evaluating how up-to-date the structural condition of the buildings is, which is vital in cases of structural renovation, earthquake or ground subsidence. In order to maintain this process, new instruments and measurement procedures are needed. It is important to consider that, in the mechanical and electrical sense, the measurement environment is highly noisy. The useful measurement data are smaller by several orders of magnitude than the noise level. This article presents the development and characteristics of a measurement system adapted to a high noise environment.
