ASCE/SEI 41 Assessment of Reinforced Concrete Buildings: Benchmarking ASCE/SEI 41 Nonlinear Dynamic Procedures with Empirical Damage Observations

May 19, 2023
Author(s)
Dustin Cook, Andrew Sen, Tarbin Basnet, Hamid Koodiani, Ariel Creagh, Abbie Liel, Russell Berkowitz, Wassim Ghannoum, Ayse Hortacsu, Insung Kim, Dawn Lehman, Laura Lowes, Adolfo Matamoros, Farzad Naeim, Siamak Sattar, Rob Smith
ASCE/SEI 41 is the consensus U.S. standard for the seismic evaluation and retrofit of existing buildings. Although the performance-based engineering standard is based on decades of research and the result of significant vetting by ASCE and other committees

The Impact of Nonstructural Damage on Building Function

December 7, 2022
Author(s)
Dustin Cook, Siamak Sattar
To reduce the impacts of disasters on communities, recent initiatives have focused on improving the performance of the building stock by designing for limited damage and downtime. Through these initiatives, researchers and engineers have highlighted the

Preliminary Recovery Categories and Times for a Functional Recovery Framework

June 27, 2022
Author(s)
Siamak Sattar, Dustin Cook, Katherine Johnson
To address the growing need for functional recovery design of U.S. built environment, a recent NIST and FEMA report recommends the development of a national function recovery framework serving as the minimum requirements to provide consistent performance

A Framework to Evaluate the Cost-Effectiveness of Recovery-Based Design

May 24, 2022
Author(s)
Juan Fung, Yating Zhang, Katherine Johnson, Dustin Cook, Siamak Sattar
Modern building codes and standards are generally focused on safeguarding public health and safety by ensuring buildings meet life safety performance objectives following an earthquake event. Certain classes of buildings, such as hospitals and schools, may

Lessons on Return to Function After the 2018 Cook Inlet Earthquake

September 30, 2021
Author(s)
Katherine Johnson, Siamak Sattar, Christopher Segura, Steven McCabe
The magnitude 7.1 Cook Inlet Earthquake of November 2018 greatly affected Anchorage, AK area residents. Although shaking likely did not exceed the hazard level for which most newer buildings are designed, disruption to normal operations was significant due

The Total Costs of Seismic Retrofits: State of the Art

May 7, 2021
Author(s)
Juan Fung, David Butry, Siamak Sattar, Steven McCabe
This article presents the current state-of-practice with respect to quantifying the total cost to retrofit an existing building. In particular, we combine quantitative, qualitative, and heuristic data to provide a taxonomy for understanding the direct and

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
