Structural Performance for Multi-hazards Program

Summary:

The objective of the Structural Performance under Multi-hazards program is to develop and deploy advances in measurement science to enhance the resilience of buildings and infrastructure to natural and manmade hazards by 2016.

Description:

This program addresses the gap between basic research and building codes, standards, and practice through measurement science research to: (1) predict structural performance up to failure under extreme loading conditions: (2) assess and evaluate the ability of existing structures to withstand extreme loads; (3) design new buildings and retrofit existing buildings using cost-effective, performance-based methods; and (4) derive lessons learned from disasters and failures involving structures. The program enhances the resilience and robustness of structures by focusing primarily on cross-cutting research topics including prevention of disproportionate collapse and disaster and failure studies, along with the specific hazards of extreme winds and coastal inundation.

This program supports the EL mission of promoting U.S. innovation and industrial competitiveness in areas of critical national priority by anticipating and meeting the measurement science and standards needs for technology-intensive manufacturing, construction, and cyber-physical systems in ways that enhance economic prosperity and improve the quality of life. The program supports the EL core competencies in resilience and fire protection. The program further fulfills a national knowledge transfer role that is not well-supported by a fragmented U.S. construction industry (ACI 318, AISC, ASCE 7). Finally, NIST has statutory responsibilities including: (1) the National Windstorm Impact Reduction Act (2004); (2) the Fire Prevention and Control Act (1974); and (3) the National Construction Safety Team Act (2002).
