Investigation of Strouhal number of iced cable model of cable-supported bridges with respect to angle of wind attack

Popis výsledku v původním jazyce

The Strouhal number is one of the most important parameter which is necessary for an analysis of the vortex excitation response of slender structures. the paper presents the method and results of wind tunnel inverstigation of Strouhal number of iced cable model of cable-supported bridges. The investigation were conducted in the Climatic Wind Tunnel Laboratory of the Czech Academy of Sciences in Telč. The methodology leading to the experimental icing of the inclined cable model in the climatic section ofthe laboratory was prepared. The shape of the ice on the cable was registred by photogrammetry and a numerical evaluation. For the aerodymanic investigations the iced cable model on smaller scale was reproduced with 3D printing procedure. The Strouhal number was determined within the range of the Reynolds number between 2810 and 12210, based on the dominant vortex shedding frequency measured in the flow behind the model. The model was orientated at three principal angles of wind attack
