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

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

Post-disaster studies are critical for measuring impact to communities, from physical infrastructure performance and vulnerabilities, to interdependencies with social and economic systems of the affected communities. The data collected in these studies

An accurate yet simple estimate of the retrofit cost plays an important role in the decision-making process of retrofitting existing buildings. Fung et al. (2018a) develop a predictive model to estimate seismic retrofit costs as a function of building
The seismic behavior of a building component (e.g., shear wall) is a fundamental attribute engineers need to assess the earthquake performance of a building. It is no surprise that component behavior is often dependent on the loading history. Repeatedly

The intent of current building codes for typical commercial and residential buildings is to safeguard against loss of life to building occupants by minimizing the probability of structural collapse during natural hazard events. However, current codes do

The National Institute of Standards and Technology (NIST) published the Community Resilience Planning Guide for Buildings and Infrastructure Systems (NIST SP 1190) in October 2015. The Guide describes a six-step process to develop a community resilience

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

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
NIST hosted workshop, Future Needs for Reducing the Fire Hazard of Materials, provided an opportunity for worlds experts to come together to discuss the challenges associated with reducing the fire hazards of existing and future products that compose the

This paper presents a methodology for analyzing wind pressure data on cladding and components of low-rise buildings. The aerodynamic force acting on a specified area is obtained by summing up pressure time series measured at that areas pressure taps times
It is well accepted that as structures are exposed to wind, stagnation planes are produced around structures. Past work by the authors demonstrated for the first-time that wind-driven firebrand showers may accumulate in these stagnation planes. While those
Civil infrastructure systems play an important role in community resilience. Without proper functioning of the infrastructure, especially power delivery, society will not recover quickly from disruptive events, such as hurricanes. In this paper, the

Presidential Executive Order 13717 (EO 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
Wildland-Urban Interface (WUI) fires have become a problem of great concern across multiple continents. An important mechanism of structure ignition in WUI fires and urban fires in Japan is the production of firebrands. During WUI fires, decking assemblies

This paper presents a framework for a probabilistic hazard assessment for the multi-hazard seismic and tsunami phenomena (PSTHA). For this work, we consider a full-rupture event along the Cascadia Subduction Zone and apply the methodology to the study area
Wildfires that spread into communities, referred to as Wildland-Urban Interface (WUI) fires, have destroyed communities in numerous countries on several continents. Large outdoor fires in Japan mainly occur after earthquakes, which may initiate complex
