Probabilistic Assessment of Occupant Comfort in Tall Buildings
Publication: Structures Congress 2009: Don't Mess with Structural Engineers: Expanding Our Role
Abstract
Modern tall buildings are expected to meet certain wind-induced drift (serviceability) and acceleration (occupant comfort) criteria to preserve the integrity of their building cladding system, interior finishes, and operation of elevator system and to ensure occupant comfort due to building motions. In light of the significance of habitability requirements of tall buildings, this paper presents a probabilistic framework to evaluate a building's habitability performance at different recurrence interval winds under the influence of parametric uncertainties. An occupant comfort based checking procedure is introduced that may lead to a practical probabilistic design procedure for evaluating the habitability of tall buildings. The perception index or probability of failure for this assessment can be related to the occupants' reactions and consequences. The consequences of building failure to meet human comfort guidelines are addressed, leading to a risk-based decision analysis framework. This will aid in establishing a rational approach to ascertain the need of supplementary damping devices.
