Determination of Wind Loading Patterns and Structural Response of Constructions in Coastal Area of Croatia – Field Full-Scale Experiment

Two prominent characteristic local winds, Bora and Sirocco, are worldwide recognized and researched winds. However, there has been modest research of their effects on structures in Croatia. The Bora wind is characterized as downslope wind and it is known for its gustiness and turbulent characteristics. Both local winds have the similar distribution of mean wind speeds at standard meteorological level (10 m above the ground level) averaged at 10 minutes interval. Key differences of these local winds have been presented in this research with respect to structural dynamics. Dynamic features of winds are difficult to simulate by numerical or physical models without detailed field investigations. In the presented experimental study simultaneous measurements of wind speed profile and structural response were conducted for the first time in Croatia. The data obtained from meteorological measurements enabled us to perform statistical analysis of wind records, to describe underlying stochastic processes and to highlight differences between stated prominent local winds. The final results of described operations are extrapolated measurements in the spatial and temporal domain. Parallel to this research, the proprietary numerical model was developed which enables the input of enhanced wind series as an additional layer of validation via an independent data set.
