In case of a submerged floating tunnel (SFT), which is difficult to cast in-site underwater
construction, it is modularized on land and then assembled them in the field. Therefore, it is
influential to investigate the structural performance of the joints between the modules. A
concept of the steel-concrete composite hollow in the SFT, which stably maintains the joints,
has been proposed by applying prestressing method to resist various external loads. In this
study, the bending behavior of module joints was experimentally analyzed to evaluate the …
