In this paper, the development of a spliced girder which is called ‘SegBeam’ is introduced. SegBeam use the ‘joint block’ which composes the splicing end part of a segment and is made of higher strength concrete than the other part of segment. The joint block is used for easy match casting and resisting the stress concentration during splicing process with post tensioning. Also, joint block enables to make a variable length of segment as the joint block fabricated in advance can be moved in the form of the segment. To verify the performance, full-scale load test of a 60m-long SegBeam is carried out. The structural safety of SegBeam is guaranteed under the load exceeding the ultimate design load of the girder. The applications of the SegBeam in the real construction field are also introduced. |
