Annotation: The article is devoted to studying leeward waves in urban area with the altitudinal buildings possessing properties of interference effect of wave formation which can lead to multiple increasing of wind loading that is not considered by building standards. The characteristics of the leeward waves depending on the atmosphere state and the sizes of wave formation source, the geometrical sizes of area where wave loadings are essential and vibration strengthening are possible, energy transferring is estimated by leeward waves taking into account dissipation and attenuations effects. There have been received results of fields calculations of arising leeward waves on the example of a situation of two altitudinal buildings where the character of waves distribution of and wind pressure arising with this are defined. The additional pressure value depends on the geometrical building sizes and to their mutual location. Interaction of leeward waves leads to interference picture and, as the consequence, to the local wave pressure enhancing. The new concept the interference factor is entered, allowing to estimate of wind, strengthening influencing on buildings in the conditions of territories building.
Keywords: altitudinal building, urban area, wind loads, leeward waves, interference effect, interference factor.
