Practical CFD Simulations of Wind Tunnel Tests

December 1, 2013
Author(s)
Dilip K. Banerjee, Scott Hemley, Randall J. McDermott, Donghun Yeo, Marc L. Levitan
Computational fluid dynamics (CFD) has the potential of replacing wind tunnel testing in many wind engineering applications. Validated CFD software could enable structural engineers and builders to calculate wind effects on buildings for which no

An Assessment of Methods for Determining Wind Loads

January 1, 2013
Author(s)
Emil Simiu, Chris Letchford, Nicholas Isyumov, Arindam Chowdhury, DongHun Yeo
The purpose of this work is to present an assessment of methods for determining wind loads on buildings and other structures that warrant comment, correction or improvement. The assessment is intended to serve as a resource as a new version of the American

Meteorological extremes

December 28, 2012
Author(s)
Franklin T. Lombardo, Adam L. Pintar, Antonio Possolo, Emil Simiu, DongHun Yeo
This entry reviews basic principles of the statistical analysis of large extreme values (EVs), the role of simulations for the development of relevant meteorological data sets, the interaction between the extreme value modeling process and its application

NIST ADVANCES IN COMPUTER-AIDED AND COMPUTATIONAL METHODS IN WIND ENGINEERING

October 19, 2012
Author(s)
Dong Hun Yeo, Franklin T. Lombardo, Dilip K. Banerjee, Eric J. Letvin, Emil Simiu, Marc L. Levitan, Florian A. Potra
The paper summarizes recent research and development of computer-aided and computational methods in wind engineering at the National Institute of Standards and Technology (NIST). Specific topics to be covered include: 1. Time-domain database-assisted

An Assessment of Methods for Determining Wind Loads (NIST TN 1738)

March 1, 2012
Author(s)
Emil Simiu, Chris Letchford, Nicholas Isyumov, Arindam G. Chowdhury, Dong Hun Yeo
The purpose of this work is to present an assessment of methods for determining wind loads on buildings and other structures that warrant comment, correction or improvement. The assessment is intended to serve as a resource as a new version of the ASCE-7

Database-Assisted Design for Wind: Multiple Points-in-Time Approach

December 22, 2011
Author(s)
Dong Hun Yeo
One of the problems encountered in the estimation of wind effects on high-rise structures is the development of combinations of such effects as translational responses and the rotational response to wind, and/or forces and moments at various cross sections

DEVELOPMENT OF LARGE DIRECTIONAL WIND SPEED DATABASES

April 25, 2011
Author(s)
Dong Hun Yeo
For structures sensitive to wind directionality, methods for the estimation of wind effects require the use of time series of directional wind speeds with length exceeding the length of the MRIs of interest. This study proposes a procedure for generating

A PROPOSED TECHNIQUE FOR DETERMINING AERODYNAMIC PRESSURES ON RESIDENTIAL HOMES

February 16, 2011
Author(s)
Tuan-Chun Fu, Aly Mousaad Aly, Arindam Chowdhury, Girma Bitsuamlak, DongHun Yeo, Emil Simiu
Wind loads on low-rise buildings in general and residential homes in particular can differ significantly depending upon the laboratory in which they were measured. The differences are due in large part to inadequate simulations of the low-frequency content

Database-Assisted Design for Wind: Veering Effects on High-Rise Structures

August 15, 2010
Author(s)
Dong Hun Yeo, Emil Simiu
Atmospheric boundary layer winds experience two types of effects due to friction at the ground surface. One effect is the increase of the wind speeds with height above the surface. The second effect, called the Ekman layer effect, entails veering -- the
