  • Research Plan for the Study of Seismic Behavior and Design of Deep, Slender Wide Flange Structural Steel Beam-Column Members (NIST GCR 11-917-13) PDF 4.5MB Editorial Revisions Only

    Synopsis: This report summarizes the recommended tasks, approximate schedule, and order of magnitude budget for a multi-phase, multi-year experimental and analytical research plan investigating the behavior of deep, slender wide-flange structural steel beam-column members. Work has been split up into three primary research components related to member, subassemblage, and system studies. The term member refers to an individual beam-column element, excluding connections to other elements in a building frame. The term subassemblage refers to a combination of beam and column elements representing a portion of the building frame. The term system generally refers to the overall building frame.

    Source/sponsorship: The report was produced by the NEHRP Consultants Joint Venture, a partnership of the Applied Technology Council and the Consortium of Universities for Research in Earthquake Engineering.

  • Research Needs Identified During Development of the 2009 NEHRP Recommended Seismic Provisions for New Buildings and Other Structures PDF 219KB

    Synopsis: As part of its efforts to regularly update the NEHRP Recommended Seismic Provisions for New Buildings and Other Structures, the Building Seismic Safety Council (BSSC) is charged by FEMA to identify research needed to advance the state of the art of earthquake-resistant design and to serve as the basis for future refinement of the Provisions. During the project to generate the 2009 edition of the Provisions, the various working groups identified specific needed research that was beyond the scope of the 2009 Provisions update.

    Source/sponsorship: The report was prepared by the BSSC, a council of the National Institute of Building Sciences, with support from FEMA.

  • Research Required to Support Full Implementation of Performance-Based Seismic Design (NIST GCR 09-917-2) PDF 595KB

    Synopsis: This report identifies the research required for the nation to take full advantage of performance-based seismic design (PBSD) by describing 37 research topics in some detail. The bulk of this research is aimed at generating in-depth data about the performance, over a full range of seismic loadings, of building materials, systems, and components found in both new and older buildings. These data will serve as the basis for a library of fragilities—mathematical relationships between seismic loading and damage—that is sufficient to model most buildings in this country. A second highly critical task is to determine the performance expected from use of prescriptive code or standards requirements in designing new buildings and retrofitting existing buildings. The results of this task will not only improve the codes and standards but also will facilitate an orderly transition to wide use of PBSD in the next decade.

  • The Missing Piece: Improving Seismic Design and Construction Practices (ATC 57) PDF 3MB

    Synopsis: This report describes a proposed program of problem-focused research, technical support, and outreach designed to address a technology transfer gap within NEHRP. This gap, which limits the adaptation of basic research knowledge into practice, was first identified by representatives of the design and construction industry in the late 1990s. They recommended that NEHRP develop "a much expanded, problem-focused knowledge development, synthesis and transfer program" to improve seismic design and construction practices. The Applied Technology Council (ATC) solicited industry input on the design of this program through a workshop and issue papers. The resulting design, detailed in this report, is organized around two subject areas and five program elements. In addition to describing these elements, the report discusses personnel and budgetary requirements and other practical considerations related to program implementation.

    Source/sponsorship: The report was prepared by ATC in cooperation with leading professionals from the seismic design and construction industry, who volunteered substantial time and effort to the project. Financial support was provided by NIST.
