Structural Safety in Hurricanes, Fires, and Earthquakes (+$2 million)
Each year, the United States suffers an estimated $52 billion in property damage, disruption of commerce, and lost lives due to natural disasters such as hurricanes, wildland fires, and earthquakes. A single major event—a big earthquake or hurricane—potentially could cause some $80 billion to $200 billion in economic losses in the affected areas.
The tragedy caused by Hurricanes Katrina and Rita in August and September 2005 underscores the growing risk to society from natural disasters. One important way in which we can reduce these costs and mitigate the loss of human life and property is by making our structures—buildings, bridges, tunnels—as well as our key utility networks—electric power, water, sewage, communications, financial and data networks—more resilient and resistant to disasters. This requires both developing a scientific basis for design decisions and translating that science into practice. Current building design practices, for example, do not attempt to consider how well a structure would perform in an uncontrolled fire because there is no accepted science-based set of tools to evaluate the fire performance of entire structures under realistic fire conditions.
Proposed NIST Program
NIST is an internationally recognized leader in researching and understanding the effects of earthquakes, wind, wildfires, and other extreme events on structures. NIST works with other government agencies, universities, and the private sector to develop technologies, tools, standards, and practices to better predict the extent of damage from natural disasters, mitigate their impact, and help prevent structural and infrastructural failures in their wake.
The goals of this initiative are to develop:
This research effort should result in:
