Selecting and Scaling Earthquake Ground Motions for Performing Response-History Analyses

November 15, 2011
Author(s)
Andrew Whittaker, Gail Atkinson, Jack Baker, Jonathan Bray, Damian Grant, Ronald Hamburger, Curt Haselton, Paul Somerville
The primary objective of this task was to develop guidance for selecting, generating, and scaling earthquake ground motions for effective use in performing response history analyses for use in performance-based seismic engineering. The need for such

Annual Report of the National Earthquake Hazards Reduction Program for Fiscal Year 2010

November 1, 2011
Author(s)
John(Jack) R. Hayes Jr., Steven L. McCabe, Edward Laatsch, Joy Pauschke, David Applegate, John Filson, Tina M. Faecke
This annual report of the National Earthquake Hazards Reduction Program (NEHRP) for fiscal year 2010 is submitted to Congress by the Interagency Coordinating Committee (ICC) of NEHRP, as required by the Earthquake Hazards Reduction Program Reauthorization

Nonlinear Dynamic Analysis of Structures Using Modal Superposition

April 13, 2011
Author(s)
Kevin K. Wong
A fast nonlinear dynamic analysis algorithm based on modal superposition of structural response incorporating both material and geometric nonlinearities is proposed. Because linear modal superposition has found great acceptances in performance-based

A Direct Analysis Method for Drift-Sensitive Steel Moment Frames

February 17, 2011
Author(s)
John L. Harris
Design interaction equations for steel members in a moment frame are formulated based on inelastic member capacities that account for geometric imperfections, residual stresses, second-order effects, and, in some cases, eccentric loading. The analytical

Annual Report of the National Earthquake Hazards Reduction Program for Fiscal Year 2009

October 1, 2010
Author(s)
John(Jack) R. Hayes Jr., Edward Laatsch, Joy Pauschke, David Applegate, John Filson
This report about the National Earthquake Hazards Reduction Program (NEHRP) during fiscal year 2009 is submitted to Congress by the Interagency Coordinating Committee (ICC) of NEHRP, as required by the Earthquake Hazards Reduction Program Reauthorization

Concrete Model Building Subtypes

September 30, 2010
Author(s)
William T. Holmes
This study was conducted by the National Institute of Building Sciences Building Seismic Safety Council (BSSC). The goal was to develop standardized categories for older concrete buildings that incorporate more detail than those included in the standard

Applicability of Nonlinear Multiple-Degree-of-Freedom Modeling for Design

September 15, 2010
Author(s)
Michael Valley, Mark Aschheim, Craig Comartin, William Holmes, Helmut Krawinkler, Mark Sinclair
In 2008, NIST initiated Task Order 68241 entitled "Improved Nonlinear Static Seismic Analysis Procedures – Multiple-Degree-of-Freedom Modeling." The purpose of this project was to conduct further studies on multiple-degree-of-freedom effects as outlined in

NONLINEAR MODAL ANALYSIS AND SUPERPOSITION

July 25, 2010
Author(s)
Kevin K. Wong, John L. Harris
Linear modal analysis and superposition technique has been used extensively in earthquake engineering and seismic applications for decades, and it is here extended to the nonlinear domain by representing the material nonlinearity using the force analogy

Annual Report of the National Earthquake Hazards Reduction Program for Fiscal Year 2008

August 3, 2009
Author(s)
John(Jack) R. Hayes Jr., Edward Laatsch, Joy Pauschke, David Applegate, John Filson
This annual report of the National Earthquake Hazards Reduction Program (NEHRP) for fiscal year 2008 is submitted to Congress by the Interagency Coordinating Committee (ICC) of NEHRP, as required by the Earthquake Hazards Reduction Program Reauthorization

Research Required to Support Full Implementation of Performance-Based Seismic Design

April 15, 2009
Author(s)
William Holmes, Andre Filiatrault, John Hooper, Nicolas Luco, Jack Moehle, Maryann Phipps
To encourage further development of PBSD, FEMA commissioned several action plans that included work plans and budgets, and these efforts culminated in 2002 when FEMA provided the Applied Technology Council (ATC) with funding to develop next generation
