“…To simulate the pattern of variation of natural frequencies due to the cracking of the dam, a finite element (FE) model of the dam was constructed using SAP2000 software. The model was constructed using the solid element of concrete material with the elastic modulus and density adjusted so that the natural frequency of the FE model was as close as possible to that measured in the field by Emanov et al [29]. The elastic modulus was 13 729 310 kN m −2 , which is 44.76% lower than the SAP2000 default value, reflecting some existing small cracks in the dam.…”

“…The dam is 242 m high and 1066 m long; the widths of its crest and base are 25 m and 105.7 m, respectively (figure 2). Using the standing waves technique, Emanov et al [29] observed the mode shapes of the dam. They measured ambient vibration signals at a fixed reference point and some shifted points.…”
