Structures Group


The Structures Group provides performance prediction tools to reduce the vulnerability of building and infrastructure systems to extreme events (e.g., wind, fire, earthquake, impact, blast) through cost-effective reliability-based multi-hazard approaches. The group: (1) conducts laboratory, field, and analytical research in the areas of wind engineering, structural fire safety design and retrofit, mitigation of progressive structural collapse, nondestructive evaluation, and performance of structural materials and connections; (2) provides guidance, tools, and science-based criteria for vulnerability assessment, design, and retrofit applications; (3) conducts disaster and failure investigations; and (4) supports the technical information needs of federal agencies in formulating national policies related to building and infrastructure applications.


Wind Engineering and Coastal Inundation Project—The project develops next-generation procedures for achieving designs that are safe, sustainable, and economical under extreme winds and coastal inundation, consistent with priorities described in …

Robust Structural Systems for Disproportionate Collapse Mitigation—In the context of codes and standards for structural design, the term robustness has been used to indicate the ability of a structural system to resist damage under extreme loads. Since the early …

Implementation of Joplin Tornado Recommendations Project—In March, 2014, NIST completed its investigation of the 2011 Joplin tornado and issued a final report (Final Report, NIST Technical Investigation of the May 22, 2011, Tornado in Joplin, Missouri, …

Measures of Building Resilience and Structural Robustness Project—Disaster resilience of a building or a community is the capability to quickly restore full functionality following an extreme event.  Buildings play a critical role in achieving community …
