Building-Level Seismic Performance Assessment

Ongoing
Objective: To better understand the seismic performance of buildings designed in areas of medium-to-high seismicity and to identify ways to create enhanced performance through low-damage approaches, improved code provisions, and improved analysis procedures. What is the Problem? Despite progress

Collapse Assessment of Buildings under Seismic Loading

Completed
Objective - To evaluate the collapse probabilities of a suite of steel buildings for a series of increasingly severe earthquake ground motions, and to compare these probabilities to the collapse objective presumed in ASCE/SEI 7. The probabilities of collapse will be determined using the methodology

Earthquake Risk Reduction in Buildings and Infrastructure Program

Ongoing
Objective: The Program’s objective is to develop and advance knowledge which can improve codes, standards, and design guidelines for earthquake risk mitigation of buildings and infrastructure systems with the focus on recovery-based design. These efforts supplement NIST’s role as lead agency for the

Functional Recovery of Buildings and Lifelines

Ongoing
Objective: The Functional Recovery project is designed to improve the time for recovery of key social functions via strengthening of the built environment to withstand earthquake impacts. Our efforts will advance measurement science for the assessment and design of buildings and lifelines

Improved Assessment Criteria for Performance-Based Seismic Design

Completed
Objective - Task (1): To establish a new generation of performance-based design assessment criteria that captures a component action’s dependence on loading history by conducting a set of focused experimental tests and computer simulations on eccentrically braced frame link beams. Task (2): To vet

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

Performance Criteria Development

Ongoing
Objective: To advance component-level seismic performance criteria in current design standards by conducting focused experimental tests and analytical studies. What is the Problem? Performance-based seismic engineering methodologies require a thorough and accurate understanding of component-level
Connection among three tasks under the main research plan.

Risk Evaluation and Mitigation

Ongoing
Objective: This project aims to improve techniques currently used for risk evaluation (including uncertainty quantification) and mitigation (including FRP retrofit) of structural systems and integrate them within the PBEE framework. The first phase of the project is focused on development and
