Performance Evaluation Test for Applying the Mechanical Development of the High-Strength Reinforcing Bars to the Nuclear Power Plant Structures

고강도철근 기계적정착의 원전구조물 적용을 위한 성능평가실험

If the mechanical development be applied to the Nuclear Power Plant Structures instead of the standard hook development, the problem of overcrowding re-bars in the anchorage zone can be solved and the construction quality of the concrete work will be improved. But there are some problems in applying it to the NPP structures because of the restriction on the re-bar yield strength and diameter. After the performance evaluation test for the mechanical development, we can develop the new design equation of the mechanical development length in order to solve the limitation and apply it to NPP structures.
