THE DETERMINATION OF UNFAVORABLE TRAJECTORY OF TORNADO MOVEMENT BY ANALOGY WITH ANALYSIS OF TRUSS

The article discusses the definition of unfavorable trajectory of tornadoes for the elements of the middle of the through span structure of a continuous rail truss. Contains "tornado wind rose' resulting from the calculations, allowing to define stress or displacement in this element of structure at different angles of attack of tornado. Diagrams of horizontal and vertical support reactions at the moment of tornado passing are given.
