Very large floating bridges are distinguished by their capacity to cross wide and deep waters without the need for fixed foundations. Code-based design checks of floating bridges require a great number of simulations to ensure their serviceability and safety under various load conditions. However, time-domain simulation requires tremendous computational efforts. A promising alternative is to utilize a frequency-domain approach. In this study, a frequency-domain hydroelastic modeling approach is developed for a general pontoon-type floating bridge, in which the pontoons are modeled as rigid bodies whereas the superstructure is represented using beam elements. Hydrodynamic interactions between pontoons and viscous loads are considered. This study aims to validate the method by utilizing a public-available dataset of a truncated floating bridge tested in SINTEF Ocean basin. Time-domain simulations based on SIMA are also conducted as comparisons. It is shown that the proposed approach offers reasonable estimates of modal properties and RAOs. Moreover, with linearized second-order loads and hydrodynamic interactions considered, it captures low- and wave-frequency resonant peaks with adequate accuracy.
