Wind tunnel study of axial force variation in guys of flexible mast modelWind models
Lublin University of Technology, Department of Structure Mechanics, Nadbystrzycka 38d St., 20-618 Lublin, Poland
Measurements of the axial force variation in guys of mast model subjected to wind load of three different wind structures are presented in the paper. The measurements have been carried out in the wind tunnel of Wind Engineering Laboratory at Cracow University of Techn ology. The subjects of the research are two guyed masts of triangular and square shaft cross-sections. Mean values of forces and standard deviations as functions of wind parameters and wind attack angle have been calculated. Significant influence of wind structure on the forces in guys has been confirmed as the result. Additionally there has been noticed possibility of mast vibrations at critical velocities.
