쌍계1교 재하시험에 대한 극한한계상태 해석 = Ultimate Limit State Analysis on Proof Load Testing for Ssanggye-1 Bridge

다국어 초록 (Multilingual Abstract)

Assessment of an existing structure is a big issue to confirm the structural safety since infrastructures get deteriorated and damaged. Infrastructure assessment research center (ISARC) has tried to develop and apply new techniques for safety evaluation of concrete infrastructures. In accordance with the efforts, this paper shows an analytical evaluation of load-carrying capacity of a bridge. The target is a reinforced concrete T-girder bridge named as Ssanggye-1. The measured geometry of members and estimated properties of material are the input for ultimate limit state analysis. The analysis assumes the scenario of crisis with the proof load testing accomplished beforehand. Comparison between the analytical prediction and the experimental results shows good agreement and systematizes the analytical evaluation of load-carrying capacity.
