Abstract: A submerged floating tube bridge (SFTB), or generally called Submerged floating tunnel (SFT) has never been built.

The Norwegian Høgsfjord SFTB was a concept that had gone so far to the milestone of being technically approved by the national road authority in the last 90s. Recently,...
Abstract: The current paper shows an overview of the dynamic analysis methods and models for the SFTB concept. The design basis for the Bjørnefjord in Norway is given, followed by the analysis methods for different design issues together with example results. First and second order wave loads and responses, current induced loads and response (Vortex Induced Vibration, VIV) and other types of loads and...
