After the huge East Japan Earthquake, many steel structures have been constructed using welded frame welded joints and welded foundation construction. Although steel-frame structures are regarded as earthquake-resistant structures, many steel-frame structures are built using fillet-welded frame-welded joints and welded column bases. These welded joints might have less ability to absorb energy during an earthquake. Therefore, when designing steel structures that use welded joints, it is necessary to consider the seismic resistance of column bases in particular. To confirm the safety of these unstable structures, we propose measurements using piezo-composite sensors. The measurement results suggest long-term evaluation of these structures. As described in this paper, the relation between the sensor output and the thickness of the piezo-composite sensor base plate was found quantitatively using data obtained using a measurement robot (SALLY). Next, after fabricating a piezo-composite sensor that can measure displacement when the deformation angle of the strut is 1/100 or 1/200, we verified it using a mounting test. We conducted a similar experiment using a measurement robot and compared the sensor characteristics. Herein, results obtained using the measurement robot (SALLY) for the relation between the output and displacement of piezo compound sensors is explained. The mounting test of the piezo junction sensor used under the optimum conditions for the robot measurement confirmed that the target displacement measurement can be measured from the sensor output by changing the piezo-composite sensor plate thickness.
