Application of 360 Degree Imaging and Construction Progress Documentation Platforms in Large-scale Experimental Testing: A CFS10 Case Study

July 13, 2026
Author(s)
Amanpreet Singh, Matthew Speicher, Fidence Cyizere Rukundo, Benjamin Schafer, Tara Hutchinson
Large-scale experimental testing requires documentation of construction processes and damage throughout testing. Traditional photographic records, while useful, face challenges of organization and accessibility, and ease of use. To address these issues

Unification of Multi-Source and Multi-Fidelity Fragility Functions

April 4, 2026
Author(s)
Mohammadamin Hariri Ardebili, Siamak Sattar
The derivation of fragility functions through nonlinear dynamic analysis is a domain that has garnered significant attention historically. The majority of prior research efforts have been focused on the ground motion record-to-record variability and the

Formulating, Fitting and Fusing Fragility Functions (F5)

Author(s)
Mohammadamin Hariri Ardebili, Siamak Sattar
Fragility functions derived from nonlinear dynamic analysis are a central ingredient in seismic performance assessment and risk analysis of structural systems. This technical report revisits fragility functions from a unified perspective that addresses

Functional Recovery Performance Targets Workshop Report

September 30, 2025
Author(s)
Lucy Arendt, Katherine Johnson, Siamak Sattar, Michael Valley, Divya Chandrasekhar, Laurie Johnson, Ryan Kersting
Held in October 2024, the Workshop on Functional Recovery Performance Targets was hosted by the National Institute of Standards and Technology (NIST) and managed by the Applied Technology Council (ATC-169). The workshop convened 48 interdisciplinary

TRIP$ - Transportation Risk-Recovery Investment Planning Solutions: Optimizing Earthquake Resilience & Functional Recovery of Highways

September 29, 2025
Author(s)
Aspasia Nikolaou, Angelos Tsatsis, Maria Antoniou, Juan Fung, Yalda Saadat, Fani Gelogoti, Rallis Kourkoulis, Steven McCabe
The United States (US) faces significant challenges in maintaining and modernizing its aging infrastructure, particularly in the transportation sector, which includes roadways, bridges, rail, air, ports, and pipelines. Infrastructure vulnerabilities

Estimating the Costs and Performance of Enhanced Building Design: A Case Study of Functional Recovery for New Buildings

September 17, 2025
Author(s)
Sherief Elsibaie, Yating Zhang, Juan Fung, Dustin Cook, Siamak Sattar, Peter Morris, Henry Burton, David Welch, Kamiar Anaraki
This report details the development of different structural design building archetypes and other seismic enhancements, the cost estimation process applied to those archetypes, and the economic implications and estimation of differing functional recovery

Infographic on Post-Earthquake Functional Recovery Performance

February 10, 2025
Author(s)
Katherine Johnson, Siamak Sattar, Dustin Cook
In the U.S., building codes and standards have been developed to reduce the likelihood of building collapse but do not address the loss of building functions or recovery times due to earthquakes. When scaled to the community level, negative consequences

ICSSC Biennial Progress Report for 2024: Report on Progress Towards Implementation of Executive Order 13717: Establishing a Federal Earthquake Risk Management Standard - Reporting Period: February 2, 2022 to February 1, 2024

January 23, 2025
Author(s)
John Harris, Steven McCabe
Executive Order (EO) 13717: Establishing a Federal Earthquake Risk Management Standard establishes minimum seismic requirements for new and existing buildings that will be constructed, altered, leased, financed, or regulated by the Federal Government

Infographic on Post-Earthquake Functional Recovery Performance

January 3, 2025
Author(s)
Katherine Johnson, Siamak Sattar, Dustin Cook, Sandesh Aher
This research brief provides a research summary and research advancement details for the functional recovery post-earthquake performance objective being advanced by NIST's Engineering Laboratory. A current update on the status of functional recovery

Construction Quality and Assurance for Functional Recovery Design

September 6, 2024
Author(s)
Jakub Valigura, Dustin Cook, Siamak Sattar
As part of the ACI 374A Subcommittee on Design of Reinforced Concrete Structure for Functional Recovery, the authors held six expert panel discussions with experts in various aspects of building design and construction. The goal of the discussions was to

Functional Recovery in Modern Reinforced Concrete Buildings

July 5, 2024
Author(s)
Dustin Cook, ABBIE LIEL, Amir Safiey
In the field of structural engineering, functional recovery is a new, but non-standardized building design objective intended to improve a building's capacity to maintain or rapidly restore basic intended functions after a hazard event, such as an

Assessing Structural Performance Using Energy

June 30, 2024
Author(s)
Kevin K F Wong
Buildings in seismic regions are designed to sustain significant damage during major earthquakes with collapse. Traditional linear design procedures use a force-based approach to size the building structural members. Alternatively, performance-based
