Abstract
Bundles of ropes were used as cable-stays of bridges. When the mutual distance between the ropes is less than three times the diameter (D) o ver bar, interference galloping can occur. Experiments in wind tunnel showed the susceptibility of even heavy weighted ropes to induced vibr ations. Excessive vibrations of cables were observed on the bridge in Prague in very slight winds. Spacers between the ropes suppressed the oscillations.
