Dynamic Interaction of Submerged Floating Tube Bridge and Train
Submerged Floating Tube Bridge (SFTB) offers a unique innovative solution for traversing deep/wide fjords and lakes. Constructing traditional bridges in such conditions due to depth of ocean, probable ununiform bottom topography and geology possesses a challenge for constructing pillar foundation. The passage of marine traffic together with various environmental conditions is crucial as well. Hence, SFTB is being seen as a potential solution to enhance transportation efficiency, sustainability, and connectivity while minimizing environmental impacts. This research employs advanced simulation tools, such as SIMA Riflex and MATLAB to model the dynamic interactions between the SFTB and train systems under varying oceanic conditions, including operational, rough, and extreme wave scenarios. The results underscore the critical importance of robust design and maintenance strategies to address the challenges posed by the randomness of wave characteristics and the complex dynamics of the train movement. By ensuring that SFTB and train components remain within safety and design limits, the study highlights the system’s resilience and the necessity of ongoing research to refine these models, ensuring the SFTB’s safety, comfort, and operational viability as an innovative infrastructure solution. In this study, a 700m section of 30km long SFTB is taken assuming the fixed-fixed boundary conditions at both the ends (Jin & Kim, 2018). The placing of mooring lines which are modelled as spring supports are placed at each 25 m in the mid 350m section of SFTB, in total 15 supports. The depth of center line of SFTB is 61,5m from free surface where the uniform ocean depth of 100m is undertaken. The multiple simulations were run for each wave scenarios by choosing different wave seeds so that the possible extremities due to stochastic nature of waves are included. The random wave excitations are generated using JONSWAP spectrum. The main aim of the study is to use the vertical displacement of SFTB and its coupling in train-track ...
