원전구조물의 고강도철근(550MPa) 사용에 따른 기계적이음 경제성 분석
Cost Analysis on Mechanical Splice of High-Strength Reinforcement (550MPa) used in Nuclear Power Plant Structures
초록
Because of the congestion problems, the high-strength reinforcements are expected to be used in nuclear power plant structures in the near future. According to ACI 349-13, lap splices of high-strength(550MPa) bars can be used but it is expected that lap splice length of reinforcement will be increased significantly. The increased lap splice length will be lead to increase in construction cost & period and to problems of other bar congestions. Therefore, this study will analyze the economic feasibility on mechanical splice of high-strength reinforcement used nuclear power plant structures instead of lap splice.
