This award recognizes promising and motivated early- to mid-career professionals with the confidence, skills, and sense of responsibility needed to exercise leadership by developing fellows' capacity for advocacy and leading efforts to reduce earthquake risk. Since the mid-1990s, a major thrust of the NEHRP agencies (NIST, the Federal Emergency Management Agency [FEMA]

An important thrust of the Earthquake Engineering Group's programs since that time has been to improve the PBD procedures. Research tasks undertaken in support of this goal include verification of the collapse reliability of steel frame buildings; collapse performance modeling of non-ductile concrete columns; quantification of material, loading, and modeling uncertainties; and development of improved assessment criteria for performance-based seismic design.

Development of more elegant structural systems, for both new structures and retrofit of existing structures, will make provision of seismic protection more affordable, more practical to attain, and more sustainable. Research tasks undertaken in support of this goal include the following: developing cost effective relationships between building characteristics and seismic retrofit costs and benefits; earthquake risk reduction in buildings and infrastructure; seismic performance of steel buildings in the central and eastern United States; reliability of fiber-reinforced composite systems in resilient infrastructure; advancing the seismic implementation of high-strength reinforcing bars in concrete walls; seismic assessment of pre-Northridge earthquake weak panel zones and welded column splices; and improving earthquake re-occupancy and functional recovery.

In addition to this task, NIST serves as the coordinating NEHRP agency partnering with FEMA, NSF, and USGS in assuring that building practices for federal buildings are sufficiently resilient and that the nation's building codes and standards are appropriate to achieving this goal. Accomplishments NIST successfully produced a final report to Congress on Research Needs to Support Establishment of an Immediate Occupancy Performance Objective Following Natural Hazard Evenys.7 NIST also completed a draft report to Congress on Recommended Options for Improving the Built Environment for Post-Earthquake Re-Occupancy and Functional Recovery Time.8 In addition, NIST worked with the National Security Council and the Office of Scientific and Technology Policy (OSTP)

The TechBriefs, prepared by leading authorities on each structural system, are readily available for download from the NIST and NEHRP consultants websites and are widely referenced by practicing engineers in the course of design work. During this same period of time, NIST produced through the same extramural consultant a series of eight technical reports covering such topics as the following: program plans for assessing collapse risk assessment of concrete buildings; evaluation of the FEMA P695 Methodology for assessing seismic performance factors, applicability of multi-degrees-of-freedom analysis in design, selecting and scaling earthquake ground motions for use in design and analysis, a research plan for exploring the seismic capacity of deep wide flange steel columns, a comparison of U.S.
