The present invention is a novel, disaster-resistant structure (such as a building, room, closet, enclosure, or wall) and a method for constructing or assembling the structure securely to a body of cast material such as a foundation, grade beam base, platform, slab or floor that incorporates flexible cables to resist the very high loads or impact of debris and other hazards that may occur due to high winds, tornadoes, earthquakes, or other severe storms. The structure is secured to the body of cast material by at least one flexible cable. The flexible cable can be comprised of any member from a group of cables, wires, ropes, strings, or threads. The flexible cable can also be made from a wide range of materials including steel, other metals, nylon, manila, polypropylene, polyester, polyethylene, Kevlar, Nomex or polyimides. Typical construction methods for a body of cast material include building a form work or frame that defines the shape and dimensions of the body of cast material. In the preferred embodiment of the present invention, at least one hollow tube is placed into the area defined by the form work or frame for the body of cast material. The tube is placed in a generally horizontal position, but the ends may be curved or turned upward. When the cast material is placed into the form work or frame and hardens, the tube is at least partially embedded. In the best mode, the tube is bent or curved so that the ends are not within the formwork or frame and are protruding from the body of cast material after it hardens. However the hollow tube could be straight, curved, or angled. The tube may also be woven between the conventional steel reinforcing of the body of cast material. In the preferred embodiment, the flexible cable is passed through the hollow tube so that it can be looped over the ceiling or portion of the ceiling after the structure is framed. Conventional construction methods for framing include the use of wood, metal or masonry. In the preferred ...
