Building-Level Seismic Performance Assessment

Ongoing
Objective The objective of this project is to better understand the seismic performance of buildings designed in areas of medium-to-high seismicity and to identify and evaluate ways to enhance the seismic performance of buildings through advances in design approaches, including conventional and low

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

Community Resilience Program

Ongoing
Objective - By 2028, deliver novel resilience planning and analysis methods and tools to support informed decision making by communities of all sizes. By 2028, implement multifaceted outreach, collaboration, and engagement to ensure the effective dissemination of community resilience guidance

Contaminant Control in High-Performance Buildings

Ongoing
Objective To better understand how strategies to achieve resilient buildings will impact chemical reactions, rates, and concentrations of high-priority indoor air contaminants. To develop test methods and building control strategies to reduce chemical levels in low-energy buildings, and to enable

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 by strengthening the built environment to withstand earthquake impacts. Our efforts will advance measurement science for the assessment and design of buildings and lifelines, contribute in

Hurricane Ian Study

Ongoing
Objective Conduct a research study on Hurricane Ian’s 2022 landfall in Florida to: Improve (a) coastal flood hazard characterization, including quantification of overland velocity and waves, (b) quantification of storm surge loads on buildings due to hydrostatic pressure, wave forcing, surge

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. Technical Idea In the following, the technical idea for each of the RTs is presented separately: RT1: High-Strength Reinforcement in

Performance-Based Seismic Engineering (PBSE) for New Buildings Project

Ongoing
Objective: To develop a measurement science tool by FY 2016 that is capable of directly, accurately, and efficiently simulating the initiation and progression of structural collapse, and to develop a methodology for quantifying acceptance criteria limits found in the ASCE/SEI 41 Standard [1] through

Resilience Infrastructure and Future Hazard Impacts: Tropical Cyclones

Ongoing
Objective By 2028, develop a methodology for quantifying hurricane-induced hazards, including wind speed, storm surge, waves, and associated hydrodynamic effects, with consideration of the near- and long-term effects of natural hazard evolution. Technical Idea This project will investigate and

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 the development and

Safety of Building Occupants Project

Completed
By 2016, this project aims to develop a framework for a model predicting evacuation decision-making during building fires, improving the accuracy of egress modeling tools used in performance-based design (PBD) of buildings.

Seismic Response of Reinforced Concrete Walls

Ongoing
Objective: The project includes two critical tasks identified in Performance Based Seismic Engineering (PBSE): (1) use of simplified reinforced concrete wall models in high-fidelity nonlinear dynamic analysis that have no robust experimental data validation - to be solved by thorough experimental

Structural Performance for Multi-hazards Program

Ongoing
Objective: To develop and deploy advances in measurement science to enhance the robustness of buildings and infrastructure to natural and manmade hazards. What is the technical idea? The fundamental new idea is that structural robustness can be significantly enhanced by developing reliable

Sustainable Engineered Materials

Ongoing
NIST will advance measurement science tools to reliably assess the performance of sustainable materials for the manufacturing, construction, and transportation industries. These industrial sectors must meet demands for higher performance, multi-functionality, and for longer life to ensure a

Validation of ASCE 41 Procedures in PBSE

Completed
Objective - The objective of this study is to advance first-generation performance-based seismic engineering (PBSE) methods by assessing the performance of a set of code-compliant buildings using ASCE/SEI 41 methodologies. This study focuses on steel buckling-restrained braced frames (BRBFs) and
