Fragility approach for performance-based design in fluid-structure interaction problems, Part I: Wind and wind turbines, Part II: Waves and elevated coastal structures
This dissertation focuses on a methodology for performance-based design using fragilities in fluid-structures interaction problems. Two types of fluid-structure interaction problems are investigated in this dissertation: Part I: wind-structure interaction (for wind turbine tower-base fatigue), and Part II: wave-structure interaction (for elevated coastal structures subjected to shear and uplift loading). The first problem type focuses on performance-based design of a wind turbine tower base connection subjected to wind loading using a fatigue limit state. A finite element model for wind turbines ...
