摘要

Both lecture and paper will start with an explanation of the working principles of Solar UpdraftrnPower Plants, in which Power Towers form the huge central chimney as air pressure sink. Both then turn tornthe loadings of these reinforced concrete shell structures, detailing the wind load as the dominating action.rnWe then change to response characteristics of power towers, from which their essential design principles arernderived. Further, vibration modes and instability phenomena are explained, and the non-linear structural responsernbehavior – materially and geometrically combined – is exemplified as an important property for the determinationrnof failure limit states. Finally we return to an explanation of those many advantages of solar updraft power plantsrncompared to other renewable energy sources.
