The collapse of the Tacoma Narrows Bridge in 1940 became wind engineering's founding catastrophe — a dramatic demonstration that aerodynamic forces could destroy massive structures through aeroelastic flutter. Since then, wind engineering has evolved into a sophisticated discipline combining atmospheric boundary layer theory, bluff-body aerodynamics, structural dynamics, and probabilistic risk assessment to ensure buildings and bridges survive extreme wind events while maintaining occupant comfort.
These simulations explore five fundamental wind engineering phenomena. Model the atmospheric boundary layer profile that determines design wind speeds at any height, visualize pressure coefficient distributions around buildings, observe vortex shedding and the dangerous lock-in phenomenon, assess pedestrian wind comfort using established criteria, and analyze the critical flutter speed that determines a bridge deck's aeroelastic stability limit.
