(f) Definition of the different processes or mechanisms affecting the
structural integrity of the tower: Generally, random loads caused
by the wind or variable loading caused by the blades (in the
case of wind towers) generate stress variation on the different
sections of the tower. Therefore, fatigue and fracture are the
key processes in these types of structures, but under certain
circumstances, such as offshore wind towers, other processes
such as Stress Corrosion Cracking (SCC) should be considered.
Here it is stressed that, in a general case, the combination of
defects and loads of a structure made from a certain material
then determines the integrity of the structure.
