Despite the significant hazard that tornadoes pose, much remains to be learned about the impacts of tornadoes on critical facilities in the United States. While a number of post-storm reports have documented the damage from individual tornadoes or tornado
This article discusses the background and motivation of work conducted at NIST to advance first-generation performance-based design procedures in ASCE 41.

In early October 2016, Hurricane Matthew crossed North Carolina (NC) as a Category 1 storm, with some areas receiving 0.38 m to 0.46 m (15 to 18 in) of rainfall on already saturated soil. The National Institute of Standards and Technology (NIST) funded
A tornado occurred on May 22, 2011in the populated area of Joplin, Missouri that caused 161 fatalities, the most caused by a single tornado since the NWS started keeping records in 1950. A conceptual model of protective action decision-making was developed
