Horizontal Shear Behavior of Precast Concrete Slab Track on Bridge
교량구간 프리캐스트 콘크리트 슬래브궤도의 수평전단 거동
Abstract
The concrete track on bridge should be designed to effectively cope with the behavior of the bridge superstructure. For this purpose, in general, shear keys are designed to be installed at a certain intervals on the bridge deck, and the track slab is cast on these shear keys to transfer the load induced by the relative displacement between track and bridge. In this study, to apply the precast concrete slab track on bridge, a shear key structure and its effective installation method are presented. Also, the structural behavior of this shear key has been evaluated by the laboratory mock-up test.
