Analysis of Wind Pressure Data on Components and Cladding of Low-Rise Buildings

December 1, 2017
Author(s)
Dat Duthinh, Joseph A. Main, Matthew L. Gierson, Brian M. Phillips
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 area’s pressure taps times

Experimental Investigation of Firebrand Accumulation Zones in Front of Obstacles

December 1, 2017
Author(s)
Samuel L. Manzello, Sayaka Suzuki
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

Vulnerability and Robustness of Civil Infrastructure Systems to Hurricanes

October 10, 2017
Author(s)
Shuoqi Wang, Dorothy Reed
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

A Methodology for Estimating Seismic Retrofit Costs

September 28, 2017
Author(s)
Juan F. Fung, David T. Butry, Siamak Sattar, Steven L. McCabe
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

COMMUNITY RESILIENCE OF LIFELINE SYSTEMS: SOCIETAL NEEDS AND PERFORMANCE ASSESSMENT

January 13, 2017
Author(s)
Chris Rojahn, Laurie Johnson, Thomas O'Rourke, Veronica Cedillos, Therese P. McAllister
The concept of community resilience is a complex, multi-dimensional problem that relies on social science, engineering, earth sciences, economics, and other disciplines to improve the way communities prepare for, resist, respond to, and recover from

Direct and Cascading Effects of Seismic Events on the Response of Water and Electrical Power Networks

December 22, 2016
Author(s)
Roberto Guidotti, Hana T. Chmielewski, Vipin Unnikrishnan, Gardoni Paolo, Therese P. McAllister, John W. van de Lindt
Water and electrical power networks are critical infrastructure in our communities; their disruption, e.g., due to the occurrence of hazard events, greatly affects communities' well-being, the economic and social response of the entire region and recovery

Guide Brief 5: Assessing Energy System Dependencies

December 13, 2016
Author(s)
Community Resilience Program NIST
A major aspect of characterizing the built environment is identifying key infrastructure dependencies that may exist. Some of these dependencies are obvious; others are not. This Guide Brief focuses on Step 2, understanding the built environment, and

Investigating Firebrand Accumulation over Various Scales

November 22, 2016
Author(s)
Samuel Manzello, Sayaka Suzuki
As structures are exposed to wind, stagnation planes are produced around structures. Using full-scale experiments, the authors demonstrated that firebrands may accumulate in these stagnation planes. In a subsequent full-scale study performed by the authors

Guide Brief 1 - Characterize the Population

September 30, 2016
Author(s)
Community Resilience Program NIST
This Guide Brief provides additional rationale and guidance regarding the first part of Step 2 in the Guide, “Characterize social functions and dependencies” which starts with “Characterize the population.” The intended audience is the social dimensions
