現今全球面臨能源短缺的問題，在海上發展能源已成為主流，離岸風機以支承結構形式不同而有所差別，相通點是都需要透過泥漿材料做接合。此外，在海上的離岸風機會受到來自風力及海浪力等作用，長期受到這些外力作用之下，會使得風機的泥漿接合部分產生破壞。本研究將利用有限元素軟體ABAQUS模擬離岸風機之支承結構，其泥漿接合部分將使用黏著元素取代接合材料，在不同載重型式(垂直載重、靜態與動態的水平載重)下探討接合部分之的應力分布以及變形行為，最後預測離岸風機的接合部分破壞趨勢。

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.
