Abstract |
These days, many cable-stayed bridges were constructed in accordance with the trend in Korea. At the moment, construction technology of cable-stayed bridges has been remarkably developed but design technology still relies upon foreign technology very much. The cable anchor system that is one of key technologies of cable-stayed bridge brings powerful cable tension to produce local stress concentration and to disturb stress seriously, so for safety must be designed by a local detailed analysis is required. But without a clear design standard or design theory relying on F.E.M, and engineers don’t understand theoretical basic mechanism of cable anchor system. As a result, engineers can be lose their judgement. Accordingly, this study examined theoretical design flow of fixing pipe in guide pipe-anchor system and additional considerations, in accordance with design standards at home and abroad to keep them in order and to suggest supplementary design flow.
