초고층건물의 기둥축소량 예측, 계측 및 보정 = Prediction, Field Measurement and Compensation of Column Shortening in Tall Building

다국어 초록 (Multilingual Abstract)

Tall Buildings have been popular in recent years. Tall buildings require special consideration to design and construction due to their structural features. Column shortening is one of the important technologies to be considered in. The long-term deformations of concrete cause vertical shortening on cores and columns, trigger deformations on cladding, partitions and finishes, and damage their serviceability. This also affects structural stability by inducing unexpected stress to the structural members such as outrigger. The main objective of this paper is to re-evaluate column shortening according to revised field information and to compare the analysis results with the actual field measurement. Mok-Dong Hyperion, a 69-story apartment building which is currently under construction, was chosen for the case study.
