Wind induced effects on structures governed by the Navier-Stokes equations are not adequately represented by the conventional linear analysis framework. This shortcoming is becoming important for contemporary structures, as their increasing span-lengths and heights make them more sensitive to nonlinear and unsteady aerodynamic/aeroelastic load effects. To address this challenge this book focuses on responding to following key questions: (1) What are the typical nonlinear behaviors observed from wind tunnel studies and full-scale observations and their underlying physics? (2) What are the...
