Models of strong wind acting on buildings and infrastructure

In the paper, the general concept of tornado is presented. A tornado wind distribution is analysed with use of modified Rankine, Burgers-Rott and Bjerkens vortex model. These models are very useful in the analysis of assessment of damages of buildings and infrastructure. Differences between these models are presented. The formation of the tornado and phenomena that appears during the tornado were presented. It is not easy to measure parameters of strong winds, especially tornado, in situ, due to fast movement and not predictable location, many researchers investigate the analytical models of strong wind, especially used for tornadoes. Rankine, Burgers-Rott and Bjerkens vortex models were presented in the paper. (paper)
