Measures of Building Resilience and Structural Robustness Project

Ongoing
Objective: By FY2014, develop the measurement science to assess the disaster resilience of buildings through the use of risk-based assessment and decision methods, and develop performance-based pre-standards for mitigation of disproportionate collapse of steel and reinforced concrete structures

Methods for Community Resilience Tradeoffs

Completed
Objective - To support community resilience planning in the context of multiple competing objectives, including sustainability, adaptation, and public health, by evaluating complementarities and tradeoffs. What is the technical idea? Communities face multiple competing objectives in planning

National Earthquake Hazards Reduction Program (NEHRP) Coordination

Completed
Objective - To support NIST's statutory Lead Agency role of coordinating National Earthquake Hazards Reduction Program (NEHRP) research and implementation activities and to provide leadership and management support for the Interagency Committee on Seismic Safety in Construction (ICSSC). What is the

NEHRP Extramural Research

Completed
Objective - A task order to assist NIST and the NEHRP agencies in updating the NEHRP Strategic Plan will be awarded to a policy contractor. In addition, other planned FY 2020 extramural research will be assigned by task order to the new IDIQ contractor once that award is made. It is anticipated that
