In the field of wind engineering, various aspects of scientific fields are interconnected. First, the randomness of the natural wind needs to be handled with respect to a realistic model for the location dependent gust velocity profile for the necessary return period. Second, aerodynamic aspects of the structure of interest, its geometries and its neighbouring buildings need to be considered. Third, the vulnerability towards different kinds of wind induced vibrations needs to be predicted. Finally, reliability analyses are based on profound knowledge of the structure itself and the extreme values distributions. So, methods for - and knowledge about - meteorology, aerodynamics, mechanics, and statistics are needed. All this should follow the goal to find predictions of the wind induced load situation in an extreme case which is as realistic as possible. The quality appraisement is an analysis, to confirm the level of reliability with respect to the design requirements. Basically, wind engineers are working with same approaches and the international scientific community is actively communicating. However, due to some specific particularities in different countries, there seem to be some differences with respect to the application of wind engineering. Research in the field of engineering in Germany is always very much related to application. So, in this lecture, some newly developed methods/findings and some project related applications will be presented.
