The Ting Kau Bridge in Hong Kong is a cable-stayed bridge comprising two main spans andtwo side spans. The bridge deck is supported by three towers, an end pier and an abutment. Each of thethree towers consists of a single reinforced concrete mast which reduces its section in steps, and it isstrengthened by transverse cables and struts in the transverse vertical plane. The bridge deck is supportedby four inclined planes of cables emanating from anchorages at the tower tops. In view of the threat fromtyphoons, the dynamic behaviour of long-span cable-supported bridges in the region is always animportant consideration in their design. This paper is devoted to the ambient vibration measurements ofthe bridge for evaluation of dynamic characteristics including the natural frequencies and mode shapes. Italso describes the modelling of the bridge. A few finite element models are developed and calibrated tomatch with the field data and the results of subsequent structural health monitoring of the bridge.
