Abstract

A parametric study for analytical correction using measurement results was performed to minimize errors in the predictions of column shortening in RC tall building. The parameters of the column shortening analytical correction are the execution standard of analytical correction, the value of the analytical correction, and the measurement location, and the analytical correction models with the parameters were applied to the construction sequence analysis of a 41-story RC building to compare and analyze the correction effect according to the parameter. The reduction ratio of the error value for each floor was compared with the number of corrections and the total corrected value, and it was confirmed that the error tended to be minimized when the execution standard of analytical correction was performed based on a regular interval, when the analysis correction value was corrected by the error value, and when the measurement position was measured every floor. From this, it was confirmed that the most appropriate analytical correction model can be derived by applying multiple analytical correction models to the actual analysis model.

RC 고층건물에서 발생하는 기둥축소의 예측 오차를 최소화하기 위하여 계측결과를 이용한 해석보정에 대한 변수연구가 수행되었다. 해석보정의 변수는 해석보정 시행기준, 해석보정 값, 계측 위치이며, 변수에 따른 해석보정 모델을 41층 규모의 RC 건물의 시공단계해석에서 적용하여 변수에 따른 보정 효과를 비교·분석하였다. 보정 횟수와 전체 보정량에 따른 층별 오차 값의 감소율을 비교하였으며, 해석보정의 시행기준은 일정한 간격을 기준으로 해석보정 할 경우, 해석보정 값은 오차 값만큼 보정할 경우, 계측 위치는 매 층 계측이 될 경우에 오차가 최소화되는 경향을 확인하였다. 이로부터 실제 해석 모델에 대하여 여러 해석보정 모델을 적용함으로써 가장 적합한 해석보정 모델을 도출할 수 있음을 확인하였다.
