Abstract
Offshore Engineering is a track that is growing up considerably during last decades.
Offshore wind turbines, oil platforms and other projects situated on the sea are good
examples of marine constructions. These types of structures are normally subjected to
cyclic loads that may produce significant changes in the properties of the material
during the life of the structure. This effect is also known as fatigue. Fatigue is a
process of progressive and permanent structural change occurring in a material which
is subjected to loads which produce time fluctuating stresses and strains.
In offshore structures, the fatigue damage is more important because the special
conditions of the sea and the marine environment that may accelerate the degradation
of the structure. The thesis deals with the response of prestressed concrete elements
subjected to fatigue damage in marine environment. A review of the most important
codes for calculating the fatigue damage is presented, comparing several requirements
and regulations. Finally, a methodology for calculating the fatigue damage in offshore
concrete structures is proposed, considering corrosion and the mechanical response of
the structure.
