Abstract

In this study, an analytical method was proposed to correct the analysis results and minimize the errors between column shortening predictions and real values in high-rise buildings. In this regard, the construction sequence analysis of 41-story reinforced concrete buildings was performed and the results were compared to four assumed field measurements that were divided into the column and the core. The analysis correction was applied at a stage over the error limit in the column and at all stages in the core. Since the error occurred continuously after the analysis was corrected, additional corrections of the analysis resulted in a smaller error. By applying the proposed analytical correction method, it was confirmed that the long-term shortening value can be accurately predicted.

본 논문에서는 해석결과를 보정하여 고층 건축물의 기둥축소 예측값과 실제값 간의 오차를 최소화하기 위한 해석보정법이 제안되었다. 이를 위하여 41층 규모의 철근 콘크리트 건물에 대한 시공단계해석이 수행되었으며, 해석결과는 기둥과 코어로 나뉘어 네 가지의 가정된 계측결과들과 비교되었다. 해석보정은 기둥에서는 오차 한계를 넘어서는 시공단계에서 코어에서는 모든 시공단계에 적용되었으며, 해석이 보정된 이후에도 지속적으로 오차가 발생하므로 해석보정이 자주 수행될수록 오차는 감소하였다. 이러한 과정을 통하여 제안된 해석보정 방법을 적용함으로써 장기적인 축소값이 실제값과 유사하게 예측될 수 있음을 확인하였다.
