Wind effects on tall buildings according to own measurements and code approach

Abstract

The paper presents the analysis of the wind action on tall buildings carried out in accordance with the recommendations of Eurocode 1, and with the results of own research conducted in the wind tunnel of the Wind Engineering Laboratory, Cracow University of Technology. Ten buildings of the same proportions were analyzed, five structures with the ratio of the cross-section dimensions of 1:2 and five of 1:4. The wind action on the longer side (N1) and on the shorter side (N2) were adopted in all cases of buildings. The total forces of wind pressure as well as displacements of top and bending moments at the base of the buildings were taken as the results which allowed to compare two different approaches.
