碩士 / 國立成功大學 / 土木工程學系 / 104 / Offshore wind turbine structure suffer from different types of loadings, such as wind and wave loads. The objective of this research is to analyze the stress fields of the grouted connection in the structure and predict the possible damage due to external forces. We used the finite element software ABAQUS to simulate the problem, and cohesive elements to describe the behavior of grout material. Stresses in the grouted connection due to different loading were shown. The results indicate the possibility of damage is dominated by shear. There also exists normal stress (opening) near the edges of the grouted connection when a horizontal load is acting. The damage zone may develop in the long term but further investigations and studies will be needed.
