This research focuses on the electromechanical strain-sensing behaviour of steel wires fiber and composites scale. The properties are investigated by using a uniaxial tensile test with simultaneous electrical resistance measurement. Further, this work conducts comprehensive stress analysis textile reinforced concrete (TRC) specimen in quasistatic dynamic tests integrated 3D-weaving reinforcement as piezoresistive in-situ-sensors. results compared to optical strain measurements digital image correlation (DIC). acquisition changes wire sensors enable an in-situ well better understanding mechanical response TRC under different loading scenarios.
