As part of the Homeland Security Act of 2002, Public Law 107-296, Congress enacted several levels of liability protection for providers of anti-terrorism technologies. The SAFETY Act (the Act) provides incentives for the development and deployment of anti-terrorism technologies by creating a system of risk management and a system of litigation management.

Elastic Limit	72 °F	00:30:00	9.044	9.044	0	Elastic Limit was calculated from MC/I. Where M is a yielding moment, C is distance from neutral axis to the most outer fiber of the beam, and I is moment of inertia.
Elastic Strain Limit	72 °F	00:30:00	0.00532	0.00532	0	Elastic Strain Limit was calculated from dividing Elastic Limit by Young's modulus.
