Frequency Domain Dynamic Analysis of a Floating Bridge

This paper describes the methodology used in the dynamic analysis of a floating bridge across Okanagan Lake in Kelowna, British Columbia. The design wind conditions were obtained through the analysis of wind data collected at two local airports and the bridge site. The design wave conditions were calculated using numerical wave hindcasting techniques and a short-crested sea state was modeled using a directional wave spectrum. Hydrodynamic coefficients were calculated using a two-dimensional wave diffraction model. The dynamic analysis was conducted using a frequency domain approach which provides population statistics for responses. The sensitivity of the results to changes in various parameters was evaluated, notably the influence of the node spacing along the spine beam in the structural model, and the influence of frequency dependent hydrodynamic coefficients.
