Effects of Modeling Decisions on the Lateral Performance of Cold-Formed Steel Framed Walls

October 17, 2022
Author(s)
Zhidong Zhang, Matthew Speicher, Amanpreet Singh, Tara Hutchinson, Benjamin Schafer
This study proposes a modeling protocol for the lateral performance of cold-formed steel (CFS) framed wall-lines that contain both steel sheet sheathed shear walls as well as gravity walls and may include the impact of non-structural finish on these wall

Impact of Detailing on the Lateral Performance of Cold-Formed Steel Framed Walls

June 27, 2022
Author(s)
Zhidong Zhang, Matthew Speicher, Amanpreet Singh, Tara Hutchinson, Benjamin Schafer
The main objective of this study is to investigate the impact of structural and non-structural detailing that is not directly accounted for in conventional lateral strength and ductility design of wall-lines constructed of cold-formed steel (CFS) framed

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

ICSSC Biennial Progress Report for 2018: Report on Progress Towards Implementation of Executive Order 13717: Establishing a Federal Earthquake Risk Management Standard - Reporting Period: February 2, 2016 to February 1, 2018

October 21, 2021
Author(s)
John Harris, Katherine Johnson, Steven McCabe
On February 2, 2016, President Obama signed Executive Order (EO) 13717: Establishing a Federal Earthquake Risk Management Standard. The EO establishes a minimum level of seismic safety compliance for new and existing buildings that will be constructed

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

Application of ASCE 41 to a two-story CFS building

October 22, 2020
Author(s)
Matthew Speicher, Zhidong Zhang, Benjamin W. Schafer
The objective of this paper is to summarize the evaluation results from applying the updated performance-based seismic design provisions: ASCE 41-17, on a cold-formed steel framed building sited in a location with high seismic demands. The assessment
