Abstract
For the purpose of analyzing economical and structural feasibility and obtaining core technologies in design, fabrication, ballasting, integration and maintenance of a floating mobile quay, one-sixth scale model with 50m x 30m x 5m dimension of pontoon-type concrete floating mobile quay was constructed. After turning out four individual modules (with 25m x 15m x 5m) on a floating dock, they were launched, ballasted, and then integrated by post-tensioning. Two times of ambient vibration tests were carried out for an individual module of floating mobile quay and for an integrated floating quay (with 30mx50mx5m) and the resonant frequencies and corresponding mode shapes and damping ratios were estimated. It was found that the global behavior of a structure was dominated by rolling and pitching motions and there was almost no heaving motion. Consequently the rolling and pitching modes can be estimated reasonably while the heaving mode could not be obtained by ambient vibration tests.
