Foreword
This study was conducted for Headquarters, U.S. Army Corps ofEngineers (USACE) under project 622784AT41, “Military Facilities Engineering Technologies (6.2 Exploratory Development),” PROMIS No. CFM-A011, “Seismic Rehabilitation of Concrete Frames with Infill.” The technical monitor was David C. Bohl, CECWEW. The work was performed by the Materials and Structures Branch (CF-M) of the Facilities Division (CF), Construction Engineering ResearchLaboratory (CERL). The CERL Principal Investigator was Dr. Ghassan Al-Chaar. The technical editors were Gordon L. Cohen and Linda L. Wheatley, Information Technology Laboratory — Champaign. Martin J. Savoie is Chief, CF-M, and L. Michael Golish is Chief, CF. The Technical Director of the Facilities Acquisition and Rehabilitation business area was Dr. Paul A. Howdyshell, and the Director of CERL isDr. Alan W. Moore. The author wishes to thank Dr. Dan P. Abrams for his review and input for this research project, Dr. Richard Klingler for his input, and the COE Seismic Review Panelists Joseph P. Hartman, HQ02, Ghassem Khosrownia, SPK, Thomas D. Wright, NWK, and David C. Bohl, HQ02, for the technical guidelines of the project. Thanks also go to the Seismic and Structural Engineering teammembers Dr. John R. Hayes, Jr. and Steven C. Sweeney for their review and input. CERL is an element of the Engineer Research and Development Center (ERDC), U.S. Army Corps of Engineers.
