キーワード：Segmental beams、UFC、Prestressed Ungrouted PC bars、FEM
The structural integrity of precast concrete components mainly depends on the connections between the precast structural elements. In this paper, different interface types and parameters representing the epoxy joint were considered to observe the effect of those epoxy joints on the behavior of PCa UFC hollow circular segmental PC beams. This study reports how the quality of connections affects the load bearing capacity and the failure mechanism of such structure. A weak interface will lead to a reduction of flexural stiffness and the stress transfer of in the concrete body of the specimens.
