The object of this study is to evaluate static behavior of transverse connection of slab-type modular bridge. Especially, this paper focus on evaluation that shear key and tendon force affect bending strength of transverse connection of slab-type modules. We compared and examined the bending performance of connection through a structural test (4-point bending test). This experimental results show that bending strength of transverse connection of slab-type modules are influenced a number of shear key and amounts of tendon force. So in order to apply to modular construction, it is necessary to research in connection of slab-type modules.
