Japan's social capital was accumulated and concentrated during the period of rapid economic growth. However, there are concerns about future deterioration, and it is expected that the number of facilities that are more than 50 years old will increase over the next 20 years. Therefore, there is an urgent need to maintain and update such aging infrastructure. Many steel structures are constructed using fillet-welded frame weld joints and welded substructures. Moreover, these weld joints have little capacity to absorb energy during earthquakes. Therefore, for designing steel structures incorporating welded joints, strong earthquake-resistance characteristics must be specially provided for those joints of steel welded bases. Furthermore, structural monitoring will be necessary. This report describes, using simple model structure of measurements our piezoelectric joint sensors for evaluating resistance and displacement characteristics of fillet welded Construction. On the other hand, as described in this paper, we present results for evaluating the load of resistance and displacement characteristics of piezoelectric joint sensors using a sensor measurement robot (SALLY). The introduction of the sensor measurement robot has reduced the working hours required for measurement experiments of sensor characteristics to about 1/19, which is expected to boost the cycle of sensor improvements in the future significantly. We will use SALLY to promote research on the performance characteristics of piezoelectric joint sensors.
