(MR21) Research report conducted by Texas Tech University on resistance of masonry walls to wind borne missile debris. Various concrete masonry assemblies met the performance requirements for a 250 mph F-5 tornado. (2003)

Video of the wind borne missile impact testing conducted for publication MR21 above. Concrete masonry wall withstands impact of wood plank.

The Center develops information on windstorm disaster mitigation and other wind-related subjects that can be made available to professionals and the public.

The Institute for Business & Home Safety (IBHS) recently conducted a wind test demonstration. In the video two full-scale houses are subjected to thunderstorm and straight-line wind conditions. The house on the left (the one blown off of the foundation) was built using conventional Midwestern construction standards and the house on the right (the one with minimal damage) was built to the IBHS FORTIFIED for Safer Living® standard for Midwest construction.
