Numerical Analysis of Supporting Structure for Offshore Wind Turbine on Monopile Foundation Subjected to External Loads / 離岸風機單樁基礎支撐結構受載重反應數值分析

碩士 / 國立成功大學 / 土木工程學系 / 102 / In recent years, nations over the world are actively looking for new alternative energy due to environmental problems caused by traditional energy, and wind power is one of the alternative energy that many countries are developing actively. As wind farms on land have gone developed, European countries whose wind power techniques are more developed began to develop offshore wind power. Analysis of the seismic responses of the foundation of wind turbines is the basis of the assessment of geometric dimensioning during structure designing, developing testing techniques and seismic alarm during operation.

This proposal applied ABAQUS, a software for nonlinear finite element analysis,to analyze the reaction of monopole support structure of offshore wind turbines affected by different period of acceleration of the earthquake basement. It also added infinite element in digital models to increase the efficiency and accuracy of analysis.

Mohr–Coulomb failure parameter has a significant effect on dynamic analysis. Considering Soil damping or not also has an impact on the analysis result. As the period of external forces was lengthened, the relative displacement of the top of the foundation piles increased.
