Windborne Missiles

DOE-STD-1020-2002

winds and can cause collapse of walls, columns and frames. These heavy missiles are not picked

up by winds consistent with the design criteria, they simply roll and tumble along the ground.

The tornado missile criteria should be consistent with new tornado hazard curves to be

developed using LLNL methodology (Reference D-13)

The missile wall and roof barriers recommended herein were all tested at the Tornado

Missile Impact Facility at Texas Tech University. The impact tests are documented in Reference

D-8. Structural response tests are not available for automobile impacts. Theoretical treatment of

structural response calculations are given in References D-10, D-11, and D-12. Barriers that

have not been tested such as grills, doors, wall cladding, tanks, mechanical ducts, etc should be

tested in order to certify their performance.

Several empirical equations have been proposed for estimating the impact resistance if

concrete and steel barriers. The equations were developed for use in the design of commercial

nuclear power plants, and may not be applicable to the missile criteria specified herein. See

Reference D-8 for a discussion of empirical missile impact equations.
