Database-Assisted Design for Wind: Concepts, Software, and Examples for Rigid and Flexible Buildings.
(30/05/2013)
Database-Assisted Design (DAD) represents a unified framework for analysis and design of buildings for wind loads that makes direct use of pressure time histories measured at a large number of pressure taps on one or more wind tunnel models. Local climatological information on extreme wind speeds and their direction-dependence can be used in conjunction with the measured pressures to obtain estimates of peak wind effects with specified return periods for use in structural design. Wind effects of interest may include internal forces and bending moments, demand/capacity ratios, or deflections and accelerations. Through direct use of measured pressures, rigorous accounting for...

Database-Assisted Design (DAD) represents a unified framework for analysis and design of buildings for wind loads that makes direct use of pressure time histories measured at a large number of pressure taps on one or more wind tunnel models. Local climatological information on extreme wind speeds and their direction-dependence can be used in conjunction with the measured pressures to obtain estimates of peak wind effects with specified return periods for use in structural design. Wind effects of interest may include internal forces and bending moments, demand/capacity ratios, or deflections and accelerations. Through direct use of measured pressures, rigorous accounting for wind directionality, and accurate modeling of structural dynamics for flexible buildings, DAD enables more accurate estimation of peak wind effects than is allowed by simplified procedures in current use, thus facilitating more risk-consistent designs. It is anticipated that in the not-too-distant future, pressure time series obtained by Computational Fluid Dynamics (CFD) may also be used in DAD. This report provides an overview of DAD and presents details of its implementation for both rigid and flexible buildings, for which separate software packages have been developed. The report is intended as a companion to these software packages, which are being made publicly available at . The software for rigid buildings incorporates an interpolation scheme which allows for estimation of peak wind effects using wind tunnel models whose dimensions do not precisely match the dimensions of the structure of interest. To facilitate efficient implementation, the details of the DAD procedure are presented herein using matrix notation. However, no use of matrix algebra by design engineers is required, and the accom
