an emphasis on bridges. His interests include buffeting and flutter analyses, vortex-induced
vibration, rain-wind induced vibration, nonlinear aerodynamics, Volterra theory, hurricane hazard
modeling, turbulence modeling, reduced-order modeling, fluid-structure interaction, and
computational fluid dynamics.Dr. Wu has authored 20 journal articles/book in these areas.
Seminar Title:Wind Effects on Bluff Bodies: Reduced-Order Modeling
Abstract:
Wind 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.The primary goal
of this seminar is to discuss effective analysis tools for better understanding and capturing
nonlinear and unsteady features concerning bluff-body aerodynamics (gust-induced effects) and
aeroelasticity (motion-induced effects) with immediate applications to the assessment of windinduced effects on flexible bridges, stay cables, super tall buildings, airfoils in the transonic
region or with high angle of attack, and wind turbines near dynamic stall conditions. These
features are not fully captured in the state-of-the-art analysis procedures. To accomplish this goal,
a systematic approach is detailed that focuses on identification and characterization of
nonlinearity and unsteadiness in bluff-body aerodynamics and aeroelasticity, assessment of their
impact on the performance, and development of an advanced analysis framework for modeling
and analysis. In view of the complexity and intractability of nonlinear and unsteady fluidstructure interactions using governing equations of fluid and structural motions, reduced-order
models are utilized and their efficacy is assessed.
