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

Autonomous cementitious materials formulation for critical infrastructure repair

January 17, 2024
Author(s)
Howie Joress, Rachel Cook, Austin McDannald, Mark Kozdras, Jason hattrick-simpers, Aron Newman, Scott Jones
Despite the long history of cement and concrete, there are still large gaps in fundamental knowledge of their properties development. The dire need for improved cementitious repair materials, requires a revolution in the way they are formulated and tested

A model for partially dependent component damage fragilities in seismic risk analysis

October 31, 2023
Author(s)
Jack Baker, Edward Almeter, Dustin Cook, ABBIE LIEL, Curt Haselton
This paper proposes a model to quantify dependencies in component damage in the FEMA P-58 seismic performance assessment methodology, and to simulate damage realizations with the desired dependencies. The model is compatible with the prior FEMA P-58

Assessing the Feasibility of Achieving Functional Recovery Goals through Seismic Retrofit of Existing Reinforced Concrete Buildings

September 23, 2023
Author(s)
Negar Mohammadgholibeyki, Maria Jose Echeverria, Amir Safiey, Dustin Cook, Maria Koliou, ABBIE LIEL
Damage from past earthquakes has significantly impeded post-earthquake building function, threatening community resilience, and motivating consideration of functional recovery in building design and assessment. This study examines whether it is feasible to

ASCE/SEI 41 Assessment of Reinforced Concrete Buildings: Comparison of the Nonlinear Dynamic Procedure with Other Evaluation Methods

May 22, 2023
Author(s)
Andrew Sen, Dustin Cook, ABBIE LIEL, Tarbin Basnet, Russell Berkowitz, Ariel Creagh, Wassim Ghannoum, Ayse Hortacsu, Insung Kim, Hamid Koodiani, Dawn Lehman, Laura Lowes, Adolfo Matamoros, Farzad Naeim, Siamak Sattar, Rob Smith
The U.S. consensus standard for seismic evaluation and retrofit of existing buildings, ASCE/SEI 41, establishes provisions for seismic analysis procedures that vary in complexity and fidelity. Although ASCE/SEI 41 provides detailed nonlinear dynamic

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

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

Activities and Lessons Learned from ACI Committee 133 - Disaster Reconnaissance

September 13, 2020
Author(s)
Lucas A. Laughery, Aishwarya Y. Puranam, Christopher Segura, Anahid A. Behrouzi
ACI Committee 133 Disaster Reconnaissance was established with the mission of reporting on the effects of major disasters on reinforced concrete (RC) structures. ACI 133 members monitor natural and manmade disasters worldwide to identify events that affect
