Fig. 35.6 a Example of water cooling tower, b, c cooling tower support columns
This large-scale structure is based on reinforced concrete (RC) support columns
around the perimeter (Fig. 35.6b, c). The length of the column is about 4 m. In
addition to the continuous static load, the columns are under humid environment and
concrete corrosion occurs. In the result there is need to monitoring of RC support
columns. For investigation of AE method in this direction the experiment was carried
out. The work objective of experiment is investigation of reinforced concrete cooling
tower support columns monitoring possibility by means of AE method.
