Although the highest wind speeds occur in tornadoes, the building code ignores tornado wind speeds in specifying the design wind speed for a location. Why?
What will be an ideal response?
Because a typical tornado covers a small area of ground and lasts for a small duration. Therefore, the probability that a tornado will strike a building is extremely small. Designing every building to resist tornado wind speeds is too uneconomical.
