Comparison of wind actions according to Eurocode and previous regulations

Abstract

European norms for civil engineering structures, well known as Eurocodes, are set of highly harmonized codes regarding structural issues. Main rules and recommendations for calculation of wind actions on structures are given in EN 1991-1-4 which is the basic document. Also, some advanced analysis regarding wind actions on towers and masts are given in EN 1993-3-1, with the intention to be transferred in the basic document in the later phase. This paper contains a short presentation of the main rules and recommendations for wind action analysis and their comparison with previous regulations JUS (SRPS). The main focus of the paper is on wind action on buildings and comparative numerical example is also given. Some experiences and conclusions from the process of Serbian National Annex preparation are also presented.
