The objective of this paper is to examine experimentally an applicability of health monitoring system employing TRIP(TRansformation Induced Plasticity)steels. The application of TRIP steels to assess structural performance degradation was evaluated by material tests. The magnetic characteristics of TRIP steels under tensile and compressive uniaxial loading were examined with the measurement of induced voltage. The stress-strain hysteresis and the associated magnetic alternation of TRIP steels were identified. Further more, plate-bending tests were carried out for both TRIP steels and stainless steels. The dual function of TRIP steels, serving as both a high ductility load-carrying member and a sensor to monitor damage accumulation, was confirmed.
