points near the jack demonstrate a sharp break in the curves when the load is about 80 kN (sensors S1 and S3 located at the same level) or about 120 kN (sensors S1 and S2 installed at different levels near the jack). We suppose that these features of the curves are associated with the appearance of local damages in the area of the static load application. At the same time, distant points do not show such a characteristic break on the curves (sensors S4, S6).
