The Use of Demand-to-Capacity Indexes for the Iterative Design of Rigid Structures for Wind

February 2, 2016

Author(s)

Filmon Habte, Arindam Chowdhury, Sejun Park

Estimates of wind effects on rigid buildings by database-assisted design (DAD) methods can be more accurate than those based on information available in standards. An upgraded version of DAD was developed that streamlines the wind engineering/structural

PLANETARY BOUNDARY LAYER MODELING AND TALL BUILDING DESIGN

January 1, 2016

Author(s)

Emil Simiu, Liang Shi, DongHun Yeo

Recent research into Planetary Boundary Layer (PBL) flows accounts for the difference between �neutral� and �conventionally neutral� flows. Of interest in structural engineering are �conventionally neutral� PBL flows, that is, flows affected by transport

Methodology to Analyze Wind Pressure Data on Components and Cladding of Low-Rise Buildings

December 29, 2015

Author(s)

Dat Duthinh, Joseph A. Main

This note establishes a method to analyze wind pressure data on cladding and components of low-rise buildings using the National Institute of Standards and Technology-University of Western Ontario (NIST-UWO) database. The aerodynamic pressures induced on a

Evaluation of ASCE 7-10 Wind Velocity Pressure Coefficients on the Components and Cladding of Low-rise Buildings Using Recent Wind Tunnel Testing Data

August 2, 2015

Author(s)

Dat Duthinh

In the USA, wind loads for building design are specified in a publication of the American Society of Civil Engineers (ASCE 7). The current version, ASCE 7-10, relies on wind tunnel tests that date back 30 to 50 years. In recent decades, many more test

Estimating Wind Speeds in Tornadoes and other Windstorms: Development of an ASCE Standard

June 21, 2015

Author(s)

Frank Lombardo, Tanya Brown, Marc Levitan, James LaDue

Estimation of near-surface wind fields in tornadoes has important applications in both structural engineering and meteorology. Estimated near-surface wind speeds are used in the design of nuclear power plants, safe rooms, storm shelters, and could be used

High Resolution Imagery Collection for Post-Disaster Studies Utilizing Unmanned Aircraft Systems (UAS)

November 19, 2014

Author(s)

Stuart M. Adams, Marc L. Levitan, Friedland J. Carol

This paper examines the use of unmanned aircraft systems (UAS) to capture imagery for use in post-disaster field studies at the neighborhood and individual building level. Applications of UASs in recent disasters as described in the literature are reviewed

WIND DIRECTIONALITY FACTORS FOR NON-HURRICANE AND HURRICANE-PRONE REGIONS

Measurement Science R&D Roadmap for Windstorm and Coastal Inundation Impact Reduction

January 30, 2014

Author(s)

William Coulbourne, Jon Galsworthy, Horia Hangan, Christopher Jones, Chris Letchford, Thomas Smith

Windstorms, storm surge, and other coastal inundation events caused 4,045 fatalities and property losses of $250 billion (in 2012 dollars) in the United States during the period of 1996-2012. More people are moving toward the nation's coastlines and thus

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

Generation of Large Directional Wind Speed Datasets from Smaller Synoptic Storm or Thunderstorm Data Samples

August 15, 2013

Author(s)

Donghun Yeo

For structures sensitive to wind directionality, methods for the estimation of wind effects require the use of time series of directional wind speeds covering time periods exceeding the length of the Mean Recurrence Interval of interest in design. This

Sustainable Design of Reinforced Concrete Structures through CO2 Emission Optimization

May 31, 2013

Author(s)

Dong Hun Yeo, Florian A. Potra

Efforts are being made to achieve more efficient operation of buildings with a view to reducing the construction industrys contribution to energy consumption and greenhouse gas emissions. That contribution also includes the energy embodied in structures

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
