When discussing the aerodynamic stability of a structure, in-depth knowledge of characteristics of wind prevailing at the site where the structure is to be erected constitutes an engineering input of vital importance to adding substance to the discussion.<BR>In other words, the construction site wind condition varies with locations from the effects of surrounding topographical features. Therefore, even the structeres of indentical design, when constructed in different locations, demand different engineering considerations as regards the wind resistance capability or vibration control measurs.In addition, take onestructure and the exposureto wind is not necessarily uniform over its entire surfaces. Also, the wind effects can totally differ depending on the wind direction.<BR>This paper reviews a series of studies conducted by the authors on the effect of topography on natural wind and consequent structure responses to wind excitation focusing on some particular types of structure chosen as typical examples. The characteristics of winds of winds blowing over the hill top.small islands, or through the channel or strait, were examined and the effects of natural winds deflected by these topographical features on the structures analyzed by such wind effects prediction techniquse as the observational survey, relief map wind tunnel testing, computerized tecnique of computational fluid dynamcs (CFD), etc.
