Sažetak
The paper presents the computation results for the Dubrovnik steel cable-stayed bridge with a total span of 474 m by using real wind action. Set of data was obtained by direct measurements of the wind direction and velocity, second values, acting on the structure at the end of its construction. The Bora wind in Croatia is known as a catabatic, very cold and locally changeable wind blowing from the direction of the towards the Adriatic coastline, with the maximum measured wind gusts over 70 m/s. The recently completed measurements of the second values of wind gusts at three points, at different elevations (10, 52 and 140 m) at the pile of the Dubrovnik bridge, and the fourth measurement point, at the other end of the bridge, have made it possible to present the actual action of this highly catabatic wind (it was the first time to measure the wind profile considering the elevations). The investigations were performed according to the EUROCODE recom- mendations and they represent the basis for the development of the Croatian codes in the field of the dynamic wind action upon the structure.
