Tall and super-tall buildings are going up all over the world, notably
in east and south Asia, the Pacific Rim and the Middle East. Advances in
materials, structural design, and wind enginerring ensure that these
buildings meet strength and safety requirements. But wind-induced
building motion can cause structures to creak and groan, elevator cables
to clash, horizons to "swing," and human occupants to feel dizzy,
nausea, or highly anxious. Wind-Induced Motion of Tall Buildings
presents an overview of current research on occupant response to motion
in tall buildings. This state-of-the-art report describes the physiology
and psychology of the human perception of motion and explains the
factors that can be used to characterize a building's movement. The
authors summarize the results of field studies and motion simulator
experiments that examine human perception of and tolerance for building
motion. they survey the serviceability criteria adopted by international
standards organizations and offer general acceptance guidelines based
on peak acceleration thresholds. Finally, they identify design
strategies that can mitigate wind-induced building motion through
structural optimization, aerodynamics treatment, and vibration
dissipation or absorption. The human tolerance for wind-induced building
motion can vary greatly and poses a challenge in new buildings of
ever-increasing height and complexity of shape. property developers,
building owners, and design professionals working on tall buildings will
use this report to ensure that occupants remain comfortable and secure
in tall buildings during periods of strong wind.
