Seismic Evaluation of a 2-Story Cold-Formed Steel Framed Building using ASCE 41-17

September 29, 2020
Author(s)
Matthew S. Speicher, Ivana Olivares, Benjamin W. Schafer
The objective of this report is to assess the adequacy of new provisions in ASCE 41 for seismic assessment of cold-formed steel framed buildings. A two-story cold-formed steel (CFS) framed building that has been designed to contemporary seismic standards

Machine Learning Methods for Predicting Seismic Retrofit Costs

September 23, 2020

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

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

Loading Protocols and Backbone Curves: U.S. and Japan Perspectives

September 13, 2020

Bruce F. Maison, Kazuhiko Kasai, Matthew Speicher
With the gaining popularity of performance-based engineering, it is essential to have reliable estimates of component (e.g., steel beam or column) performance under actual earthquake loading demands. In the United States, a component backbone curve

Seismic Stability Assessment of Steel Moment Frames and Implications for Design

September 13, 2020
Author(s)
Larry Fahnestock, Shitao Shi, Matthew Speicher
Although it is clear that a building must be capable of carrying gravity loads while developing large inelastic deformations and associated lateral displacements during a large earthquake, achieving this performance objective in day-to-day practice still

Effective Plans for Hospital System Response to Earthquake Emergencies

August 28, 2020
Author(s)
Luis Ceferino, Judith Mitrani-Reiser, Anne Kiremidjian, Gregory Deierlein, Celso Bambaren
Hospital systems play a critical role in treating injuries and preventing additional deaths during disaster emergency response. Natural disasters hinder the ability of hospital systems to operate at full capacity. Therefore, it is important for cities to

A Predictive Modeling Approach to Estimating Seismic Retrofit Costs

February 20, 2020
Author(s)
Juan F. Fung, Siamak Sattar, David T. Butry, Steven L. McCabe
This paper presents a methodology for estimating seismic retrofit costs from historical data. In particular, historical retrofit cost data from FEMA 156 is used to build a predictive model to estimate retrofit costs as a function of building
