포스트텐션 전이 플레이트의 효율적 설계를 위한 해석적 연구 = The analytical study on the effective structure design of the post-tensioned transfer plate

다국어 초록 (Multilingual Abstract)

Transfer member is an effective solution to connect the different plan shapes between the upper and the bottom level. However, its critical issue is the difficulty of realization of long-span when applying conventional reinforced concrete to the transfer member. In addition, many reinforcements is required, and the space plan can be inevitably hard due to the increased depth of the member. This report examines the results of an analysis and case study of the Post-tension System applied to transfer plate. According to the case study, parameters include the number of floors, span lengths, and the average precompression. In analytical examples, the average precompression and the member depth have been proposed as the main parameters to determine the efficiency of the Post-tensioned transfer plate.
