Abstract
The present paper describes the aerodynamic study performed on a cable fitted with a circular tube (pipe) of comparable diameter. Experimental tests were carried out in the high velocity low turbulence test section of the Politecnico di Milano wind tunnel. Typical galloping instability was observed, due to asymmetry introduced by the fitting, but also a strong torsional instability occurred. This phenomenon is not generally significant for cables, but it can appear when fittings change substantially the shape of the cable: for this reason, the study included experimental tests on this instability.
