Self‐Supporting Towers Under Wind Loads
Publication: Journal of Structural Engineering
Volume 110, Issue 2
Abstract
Alongwind and acrosswind response of self‐supporting reinforced concrete and latticed steel towers is studied analytically as well as experimentally. The analytical approach utilizes existing methods of analysis with certain modifications, while experimental study is carried out on aeroelastic models placed in uniform as well as shear flow fields generated in a medium size closecircuit wind tunnel. Results obtained are compared with measured prototype data and the comparison is found to be satisfactory. Experimental results further indicate that towers can be modeled adequately with respect to their mass and stiffness distribution without adding discrete masses. For prediction of alongwind response however, the models can not be relied upon unless these are tested in a boundary layer flow with adequate turbulence intensities.
