life of the asset and the safety of its users. For the degradation of communication structures, several factors are involved, for example, the characteristics of the material used,
of the construction process, of the environment and of the use of the structure. Still, the
most common pathologies in steel communication structures are: paint degradation,
steel corrosion and cleaver cracks [3] (Figure 8.5).
In some cases, it is possible to observe the fracture of bolts in connections between
adjoining monopole sections. Such situations can occur due to unexpected flexibility
