Following recent tornadoes, terms of specially trained architectural and engineering faculty conducted onsite examinations and research of building damage. It was concluded that tornado damage to buildings is predictable. A trained architect or engineer can establish, before a tornado strikes, those portions of the building that will offer the greatest protection to the occupants. The characteristics of tornadoes are explained in text and illustrations. Case studies are given of three school buildings hit with different, intense tornadoes. The hazardous and protective elements of the buildings are identified, and the tornado shelter quality of portions of these buildings rated as primary or secondary shelter. The purpose of this brochure is to assist architects and engineers to design facilities that offer tornado protection, and administrators to identify the best available shelter space. (Author/MLF)
