Associating Disaster Deaths with Risk Profiles

September 28, 2020
Author(s)
Stanley W. Gilbert, Jennifer F. Helgeson, David H. Webb, Juan F. Fung, Anand M. Kandaswamy
In this paper we set out to identify which “risk profiles” contribute most to deaths in disasters. A risk profile represents an identifiable group of people who would be at risk of death in a disaster through some mechanism. Four risk profiles were

Machine Learning Methods for Predicting Seismic Retrofit Costs

September 23, 2020
Author(s)
Juan F. Fung, Siamak Sattar, David Butry, Steven L. McCabe
Aging building clusters all around the world, especially in high seismic regions, will require a retrofit approach to improve the resilience of the built environment. One of the main challenges of retrofitting existing buildings is the associated cost

Economic considerations for recovery-based design

September 20, 2020
Author(s)
Juan Fung, Dustin Cook, Yating Zhang, Katherine Johnson, Siamak Sattar
Current building design practice targets life safety performance for the design-level earthquake. While some buildings (e.g., schools, hospitals) may be designed for higher performance, the actual performance of most residential and commercial buildings

Community Resilience-Focused Technical Investigation of the 2016 Lumberton, North Carolina Flood: An Interdisciplinary Approach

August 1, 2020
Author(s)
John W. van de Lindt, Walter G. Peacock, Judith Mitrani-Reiser, Nathanael Rosenheim, Derya Deniz, Maria Dillard, Tori Tomiczek, Andrew Graettinger, Patrick Crawford, Kenneth W. Harrison, Andre Barbosa, Jennifer Tobin, Jennifer Helgeson, Lori Peek, Mehrdad Memari, Elaina Sutley, Sara Hamideh, Donghwan Gu, Stephen Cauffman, Juan Fung
In early October 2016, Hurricane Matthew crossed North Carolina (NC) as a Category 1 storm, with some areas receiving 0.38 m to 0.46 m (15 to 18 in) of rainfall on already saturated soil. The National Institute of Standards and Technology (NIST) funded

A Predictive Modeling Approach to Estimating Seismic Retrofit Costs

February 20, 2020
Author(s)
Juan F. Fung, Siamak Sattar, David T. Butry, Steven L. McCabe
This paper presents a methodology for estimating seismic retrofit costs from historical data. In particular, historical retrofit cost data from FEMA 156 is used to build a predictive model to estimate retrofit costs as a function of building

Social and Economic Components of Resilient Multi-Hazard Building Design

October 3, 2019
Author(s)
Katherine Johnson, Juan Fung, Siamak Sattar, Christopher Segura, Therese P. McAllister, Steven McCabe
In 2017, U.S. damages from natural hazard events exceeded $300B, suggesting that current targets for building performance do not sufficiently mitigate loss. The significant costs borne by individuals, insurers, and government do not include impacts from

Quantifying Macroeconomic Resilience Dividends in Cedar Rapids

July 17, 2019
Author(s)
Juan F. Fung, Jennifer F. Helgeson, Cheyney M. O'Fallon, David H. Webb, Harvey Cutler
Cedar Rapids, Iowa offers a unique case study in planning for increased resilience. In 2008, Cedar Rapids experienced severe flooding. Rather than simply rebuilding, the city of Cedar Rapids is investing in a resilient flood control system, as well as in

The Lumberton, North Carolina Flood of 2016: A Community Resilience Focused Technical Investigation

October 29, 2018
Author(s)
John W. van de Lindt, Walter G. Peacock, Judith Mitrani-Reiser, Nathanael Rosenheim, Derya Deniz, Maria Dillard, Tori Tomiczek, Maria Koliou, Andrew Graettinger, Patrick Crawford, Kenneth W. Harrison, Andre Barbosa, Jennifer Tobin, Jennifer Helgeson, Lori Peek, Mehrdad Memari, Elaina Sutley, Sara Hamideh, Donghwan Gu, Stephen A. Cauffman, Juan Fung
In early October 2016 Hurricane Matthew crossed North Caroline as a category 1 storm with some areas receiving 15-18 inches of rainfall on already saturated soil. The NIST-funded Center for Risk-Based Community Resilience Planning teamed with researchers

A Computable General Equilibrium Model of Cedar Rapids

September 27, 2018
Author(s)
Jennifer Helgeson, Juan Fung, Cheyney O'Fallon, David Webb, Harvey Cutler
This report presents the development of a Computable General Equilibrium (CGE) model for the regional economy of Cedar Rapids, Iowa. The general approach that this case study takes is outlined in Helgeson et al. [1] as a method to quantify the net co

Research Needs to Support Immediate Occupancy Building Performance Following Natural Hazard Events

August 21, 2018
Author(s)
Siamak Sattar, Therese P. McAllister, Katherine J. Johnson, Christopher T. Clavin, Christopher L. Segura, Steven L. McCabe, Juan F. Fung, Leslie Abrahams, Emily Sylak-Glassman , Marc L. Levitan, Kenneth W. Harrison, John L. Harris
The performance of buildings in our communities depends on multiple factors including the availability of supporting infrastructure, the original design, the current condition and capacity to resist hazard impacts, and the ability to recover functionality

Cost Estimates for the Seismic Retrofit of Federally Owned and Leased Buildings

June 25, 2018
Author(s)
Juan F. Fung, David T. Butry, Siamak Sattar, Steven L. McCabe
Presidential Executive Order 13717, Establishing a Federal Earthquake Risk Management Standard, encourages federal agencies to “enhance resilience…[to] future earthquakes” by evaluating and retrofitting existing federal buildings based on current existing

Estimating Structural Seismic Retrofit Costs for Federal Buildings

June 14, 2018
Author(s)
Juan F. Fung, David T. Butry, Siamak Sattar, Steven L. McCabe
In NIST TN 1973 [1], we develop a methodology for estimating seismic retrofit costs. The general approach is to build a predictive model of seismic retrofit costs that (1) captures the essential factors that drive costs, such as building construction type

The Costs and Losses of Wildfires

November 2, 2017
Author(s)
Douglas S. Thomas, David T. Butry, Stanley W. Gilbert, David H. Webb, Juan F. Fung
This report enumerates all possible costs of wildfire management and wildfire-related losses. It, further, compiles estimates or proposes methods for estimating the costs and losses identified. These estimates can be used for C+NVC modeling, and can also
