THE MEASUREMENT OF STRAINS IN CONCRETE WITH THE EMBEDMENT TYPE VIBRATING WIRE GAUGE

Information related to the application and performance of the embedment type of vibrating wire strain gauge is presented in this monograph. After a brief description of a typical gauge and an outline of the principle of measurement, calibration methods developed by the authors are described. Possible errors resulting from differences between the properties of the gauge and the concrete are considered. The results of tests indicate that the gauges can measure, to a sufficient degree of accuracy, the significant time-dependent strains due to creep and shrinkage in commonly used concretes. The results of a laboratory test on a reinforced concrete column enable a comparison between readings from an embedded vibrating wire gauge, resistance gauges attached to the reinforcement, and a demountable mechanical gauge applied to the surfaces of the column. Installation methods are described and an assessment is made of possible effects on the readings of briquetting the gauges before their installation. (A) /TRRL/
