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.


Robust Structural Systems for Disproportionate Collapse Mitigation—A structural system is robust if it can withstand local failures (e.g., loss of a column or other load-bearing element) without widespread collapse. Since the early 1980s, U.S. codes and standards …

Implementation of Joplin Tornado Recommendations Project—On March 26, 2014, the National Institute of Standards and Technology (NIST) completed its National Construction Safety Team (NCST) Act technical investigation of the May 22, 2011 Joplin tornado …

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 …
