| Abstract: |
The present paper focuses on dynamic action challenges for Submerged Floating Tube Bridges (SFTB) over longer spans. Response analyses have been performed in time domain for a tether concept and a pontoon concept, respectively, using 3Dfloat software. Natural periods are compared with an analytic approach. Vertical displacements and accelerations are taken out for different swell and wind generated sea load cases. |
