The Performance of Essential Facilities in Superstorm Sandy

April 4, 2014
Author(s)
Therese P. McAllister
Superstorm Sandy affected the functionality of a number of essential buildings and facilities in the flooded areas of New York and New Jersey. The flood elevations exceeded design-level floods in many locations, as defined by FIRM maps and codes and

A Simple Means for Reducing the Risk of Progressive Collapse

December 1, 2013
Author(s)
Yihai Bao, Hai S. Lew, Fahim H. Sadek, Joseph Main
A simple debonding technique is proposed to reduce or eliminate strain localization in reinforcing bars in the region of wide flexural cracks in RC beams, and as a result enhance the resistance of RC buildings to disproportionate collapse. In this study

Structural Design for Disaster Resilience

October 28, 2013
Author(s)
Fahim H. Sadek, Joseph Main, John L. Gross, Therese P. McAllister
This paper presents a brief overview of research at the National Institute of Standards and Technology (NIST) on disaster resilience of buildings, infrastructure, and communities, including component programs and projects. NIST's efforts aim at developing

Wildland-Urban Interface Fire Research Needs- Summary Report

May 14, 2013
Author(s)
Nelson P. Bryner, Erik L. Johnsson
In response to the increasing losses due to WUI fires and to ensure that measurement science keeps pace with needed improvements in materials, fire-resistant design, mitigation response, and building and fire codes, NIST sponsored the Workshop on Wildland

Development and Characterization of Continuous Feed Firebrand Generator

May 6, 2013
Author(s)
Samuel L. Manzello, Sayaka Suzuki
Evidence suggests that wind driven firebrand showers are a major cause of structural ignition in Wildland-Urban Interface (WUI) fires. While firebrands have been researched for over four decades, prior studies have focused mainly on how far firebrands fly

Structural design for fire conditions: reliability-based resistance criteria

May 4, 2013
Author(s)
Therese P. McAllister, Bruce Ellingwood
The new paradigm of performance-based fire engineering (PBFE), with its systematic approach to identifying building performance objectives, quantitative structural analysis to verify that these objectives have been achieved, and management of uncertainties

Practical Considerations for Implementing Homeland Security Models & Simulations

December 1, 2012
Author(s)
Charles W. Hutchings, Sanjay Jain, Yung-Tsun Lee, Charles McLean
Modeling and simulation (M&S) capabilities support reasoning in many domains and can provide powerful tools for homeland security analytical needs. For example, these capabilities are particularly valuable in exploring systems which are inaccessible for

Cross-sectional stability of structural steel at elevated temperatures

April 19, 2012
Author(s)
Therese P. McAllister, Mina S. Seif
There is a lack of understanding of how structural systems perform under realistic, uncontrolled fires. Current specifications for the design of steel structures in the US do not include fire effects as part of structural design. Instead, fire protection
