Abstract

Efforts are being made to perform CFD-based estimates of wind effects on tall buildings that are sufficiently reliable to allow their use in lieu of estimates based on wind tunnel measurements. For practical purposes the assessment of the quality of the CFD simulation should be based on the adequacy of the simulation of the wind effects induced in the structure by the CFD aerodynamic data, rather than on the precision with which the various parameters that define the oncoming atmospheric boundary layer wind flow are reproduced. This approach requires a capability for estimating dynamic structural response induced by simulated CFD pressures that is effective and transparent. The paper briefly describes such a capability, referred to as database-assisted design, and its potential application in the context of CFD-based pressure time histories simulation. An illustration of the use of pressure time histories to estimate structural wind effects on tall buildings is presented with reference to a 60-story reinforced concrete structure.
