This paper presents the relevance that can reach the cross-wind actions when isolated buildings with more that 50m height are designed by means of the different analysis methodologies that are stablishes in those three international codes: Eurocode, Australian and Japanese. This paper includes both cross-wind loads that are the result of periodic wind oscillations due to vortex shedding and that should unavoidably be considered in any isolated building, and wind actions that are a consequence of the frequency coupling between the vortex shedding and the fundamental frequency of the building. These actions may determine the design of the structure that has to face the horizontal actions over the building.
