철근 물량이 절감된 PSC박스거더교에 대한 정적재하실험 및 비선형해석

Static Load Test and Nonlinear Analysis on the PSC Box Girder Bridges with Reduced Reinforcements

It is reported that the amount of reinforcements for domestic PSC box girder bridges is used two times more that those for foreign PSC box girder bridges, which is considered to be irrational and uneconomical. Therefore, we have come to the conclusion through this study that the advanced design direction can reduce the amount of reinforcements under the condition that the static load test and the nonlinear analysis for the specimen of the PSC box girder bridge with reduced reinforcements which is designed by advanced design direction was carried out in order to verify the validity of the advanced design direction.
