The D.A.R.T. is a division of NASA responsible for designing and testing support forms for disaster rescue teams (throughout the United States. These forms are used to support failing structures such as building and roof collapses due to earthquake, bombings or terrorists attacks. The primary goal of the group is to provide rescue teams design criteria that will enable them to construct wooden support structures on-|site that will allow them entry into a compromised or partially collapsed struc-ture. The construction materials brought to the site consist of various sizes of top-quality dimensioned wood pieces jand heavy-duty fasteners, generally heavy gauge nails or screws. Many different designs must be constructed and tested to provide reliable data regarding the load holding capabilities of each design.
