Abstract EN
Structure of offshore platform is very huge, which is easy to be with crack caused by a variety of environmental factors including winds, waves, and ice and threatened by some unexpected factors such as earthquake, typhoon, tsunami, and ship collision.
Thus, as a main part of the jacket offshore platform, pipe is often with crack.
However, it is difficult to detect the crack due to its unknown location.
Genetic algorithm (GA) and SCE-UA algorithm are used to detect crack in this paper, respectively.
In the experiment, five damages of the pipe in the platform model can be intelligently identified by genetic algorithm (GA) and SCE-UA.
The network inputs are the differences between the strain mode shapes.
The results of the two algorithms for structural damage diagnosis show that both of the two algorithms have high identification accuracy and good adaptability.
Furthermore, the error of SCE-UA algorithm is smaller.
The results also suggest that the structural damage of pipe can be identified by intelligent algorithm.
