The dynamic effects of wind on structures always
constitute a phenomenon that is difficult to address from the
point of view of calculation. In this respect, the structural
Regulation EN-1991 (Eurocode 1) offers comprehensive treatment
of this type of load and its effects on structures.
In this project, an advertising structure was analysed, the singularity
of which resided in its great slenderness, and in the fact that
the control of displacements and the evaluation of the dynamic
effects on the structure constituted the main difficulties of
the analysis. To carry out this analysis, a detailed model was
constructed in finite elements and, with the aid of custom-programmed
tools, a rigorous treatment of the action of the wind and its
dynamic effects was carried out in accordance with the reference
Regulation EN-1991.. |
