N2 - After a severe earthquake disaster, the building structure will be seriously damaged by the seismic force. Applying plastic energy dissipation of members with IoT functionality is an excellent technique to swiftly assess the structure’s remaining life. In the previous study, a method to evaluate the cumulative damage degree of steel was proposed through the reverse analysis of the heat generation characteristics of steel plastic deformation. This paper proposes a damage detection system, based on the damper’s plastic energy dissipation. Due to the rigidity of the column, setting dampers directly on the column cannot effectively exert its function. By setting columns both ends of which are hinged in the frame and installing knee dampers on them, it is possible to evaluate the drift angle and damage degree of the frame structure better. We place this damage detection system in the loading frame to apply static cyclic loads. With the drift angle as the target, the inverse analysis of the temperature rise which is measured by sensors caused by a damper in plastic deformation can be carried out, and the drift angle of the frame structure can be calculated. This damage detection system can display in real time the drift angle, the column foot’s cumulative plastic damage, and the instant when the plastic hinge first appears.
