Prediction and Measurement of Differential Column Shortening in High-rise Building Structures

고층건물의 부등축소량 예측 및 계측

A Hybrid Wall System(HWS) building, Kolon Bundang Tripolis was instrumented to measure the vertical deformation of core-walls and columns. The vertical shortening of individual members were measured at selected floor levels such as 1F, 12F, 25F, and 34F. The measurement has been taken during one year after the construction was started. Together with the measurement, concrete property tests were performed in the laboratory using the concrete obtained in the field. The measured vertical shortenings were compared with the calculated prediction values and the satisfactory agreement was obtained.
