Sažetak
Motorway A1 in Croatia is exposed to the gusty north wind “bora”, exceeding 250 km/h. The motorway section situated on the slopes of the Velebit Mountain is very frequently closed for traffic, precisely due to safety requirements. This creates the need for adequate protection using specially designed structures. The paper describes the interdisciplinary approach of the research (meteorology, aerodynamics, structural engineering, road designing, etc.), presenting results of several research stages. At the beginning, significant results of mathematical model of airflow was provided detecting endangered motorway sections. Several types of wind barriers were tested in the recirculation wind tunnel. So called test sections were built along the motorway, in order to maintain the experimental field in scale 1:1. Different types of wind barriers built on the motorway embankment or viaduct are presented as well. In order to validate the presumed results, special method of dynamic measurements (DMV) of wind parameters is established. Efficiency of implemented structures is presented through the results of dynamic measurements along the motorway test sections.
