Abstract
Description
There is a significant need for additional research on the
impact effects of the medium-weight class of missiles which are, by
far, the most common. These missiles primarily affect residences,
schools, nursing homes, and light commercial buildings which have not
been specifically designed to resist missile impact. Since people
are advised to seek shelter in these buildings, it is important for
the engineer to know what types of tornado-generated missile impacts
the walls will resist. Thus, the intent of this project is to
initiate a comprehensive investigation to evaluate the impact
resistance of common wall systems to medium-weight tornado-generated
missiles.
Research Objectives
Specific objectives of the research are:
1. Develop an experimental facility capable of accelerating
potential tornado-generated missiles such as a 2 in. x
4 in. timber plank up to velocities of 150 mph,
2. Conduct impact tests on a series of commonly encountered
wall configurations and to obtain the velocities of penetration and/or perforation, and
3. Determine from the preliminary investigation which types of
walls provide more resistance than others to the impact of
postulated tornado-generated missiles.
