Abstract
Hailstorms are capable of inflicting a large amount of damage on building roofs and facades. This research focuses on the prediction of hail damage so that measures can be taken to reduce this damage. Hail characteristics (size, recurrence intervals, etc.) and haildstone impacts on building facades are investigated. The vertical and horizontal components of velocity of a hailstone are treated separately. Measurements and predictions of the vertical velocity are presented. Horizontal velocities of hailstones in gusty winds beneath thunderstorms are estimated using a step by step approach. A brief description of the experimental apparatus used in simulating hail impact on building materials is given. Finally, a method to predict the damage to buildings, using the theory of plate dynamics is outlined.
