Probabilistic Performance Criteria for Tall Buildings Subjected to Wind
Database-assisted design (DAD) for wind loads consists of (1) using simultaneous measurements of wind-induced pressure time histories at a large number of taps on a model structure’s envelope, and (2) using those time histories to estimate the structural response in each member, both for rigid  and flexible buildings . DAD allows the development of reliability procedures to estimate probabilities that the structure will satisfy specified performance criteria under extreme winds . In this paper we review relevant material from  and outline such a procedure for tall, flexible buildings. The internal forces and their combinations, as they appear in design interaction formulas, are affected by climatological, micrometeorological, aerodynamic, and mechanical parameter uncertainties. The reliability procedure we propose accounts for those uncertainties and integrates information on the directional wind climate and the building’s directional aerodynamics.
