معرفی کتاب Selecting and Scaling Earthquake Ground Motions for Performing Response-History Analyses
The NEHRP Consultants Joint Venture is a partnership between the Applied Technology Council (ATC) and the Consortium of Universities for Research in Earthquake Engineering (CUREE). In 2007, the National Institute of Standards and Technology (NIST) awarded a National Earthquake Hazards Reduction Program (NEHRP) “Earthquake Structural and Engineering Research” contract (SB1341-07- CQ-0019) to the NEHRP Consultants Joint Venture to conduct a variety of tasks, including Task Order 69220 entitled “Improved Procedures for Selecting and Scaling Earthquake Ground Motions for Performing Response History Analysis.” The primary objective of this task was to develop guidance for selecting, generating, and scaling earthquake ground motions for effective use in performing responsehistory analyses for use in performance-based seismic engineering. The need for such guidance was identified in the ATC-57 report, The Missing Piece: Improving Seismic Design and Construction Practices (ATC, 2003), which defines a roadmap for the NIST problem-focused research and development program in earthquake engineering. Following a thorough study of the state of the practice with regard to selecting and scaling ground motions for nonlinear response-history analysis of buildings, the project team developed a list of key challenges facing design professionals tasked with selecting and scaling earthquake ground motions. Based on the findings identified, and considering the potential for impacting design practice in the nearterm, the following topics were chosen for study: (1) selection of ground motions based on the Conditional Spectrum; (2) response-spectrum matching; and (3) nearfault ground motions and fault-rupture directivity. To encourage consensus and consistency in the state of the practice going forward, recommendations related to selecting and scaling ground motions for design and performance assessment of lowand medium-rise buildings, and a discussion on best practices for applying the current rules in building codes and standards, are provided. The NEHRP Consultants Joint Venture is indebted to the leadership of Andrew Whittaker, Project Director, and to the members of the project team for their efforts in developing this report. The Project Technical Committee, consisting of Gail Atkinson, Jack Baker, Jonathan Bray, Damian Grant, Ronald Hamburger, Curt Haselton, and Paul Somerville performed, monitored, and guided the technical work on the project. The Working Groups, including Norman Abrahamson, Ana Luz Acevedo-Cabrera, Riccardo Diaferia, Connor Hayden, and Ting Lin conducted the problem-focused studies. The Project Review Panel, consisting of John Egan, Robert Kennedy, Charles Kircher, Nicolas Luco, Robin McGuire, Jack Moehle, and Michael Willford provided technical review, advice, and consultation at key stages of the work. A workshop of invited experts was convened to obtain feedback on the preliminary findings and recommendations, and input from this group was instrumental in shaping the final report. The names and affiliations of all who contributed to this report are provided in the list of Project Participants. The NEHRP Consultants Joint Venture also gratefully acknowledges Jack Hayes (NEHRP Director), Steven McCabe (NEHRP Deputy Director), Kevin Wong (NIST Project Manager), and Helmut Krawinkler (FEMA Technical Monitor) for their input and guidance in the preparation of this report, Ayse Hortacsu for ATC project management, and Peter N. Mork for ATC report production services.
