Effects of analytical correction methods based on measurement results for column shortening

Accurately reflecting the construction process at the site in the construction sequence analysis for predicting the amount of vertical shortening is difficult. To increase the prediction accuracy, a method of calculating rational analytical correction values for all floors and column lines with limited measurement data was proposed. In this study, the analytical correction method based on measurement results for column shortening was verified by the measurement data in the actual building, and the effect of analytical correction was analyzed. While analyzing the effect of the analytical correction of the actual measurement model, it was confirmed that the prediction can be improved by comparing the error reduction in the completion stage and applying the measurement data in the intermediate stage of the construction sequence analysis. In addition, it was judged that the effect of the correction increases as it approaches the completion stage.
