Abstract

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