Abstract EN
This study investigates the applicability of an embedded EM sensor using a series of experimental studies.
To verify the embedded EM sensor, the magnetic hysteresis of various types of PS tendons is measured.
After that, the embedded EM sensor is embedded into the concrete and the possibility of obtaining measurements is verified.
Finally, the downscaled PSC girder specimen having a sheath with a different curvature is fabricated and the influence of the sheath curvature is investigated.
The magnetic hysteresis was changed constantly even though the type of PS tendon was changed, and the embedded EM sensor can measure the magnetic hysteresis, even in the concrete and curved sheath.
The area of magnetic hysteresis was decreased according to the increase in the tension force, but the actual values were different according to the number and cross-sectional area of tendons and the initial state of sensors.
To compensate for the measured data, the tensile force was converted to the tensile stress and the area ratio was used to compensate for the initial value of the EM sensor.
According to the test results, the embedded EM sensor could be applied to the actual PS girder and it can measure the actual tension, which includes the friction loss.
