dc.description.abstractIt is important to predict the long-term deformation of steel reinforced concrete (SRC) columns especially for high-rise buildings. This research aims to modify the existing creep and shrinkage models for SRC columns. Modified models are suggested by inserting appropriate coefficients to consider the delayed long-term deformation of SRC columns resulted from the slower moisture diffusion due to the wide-flange steel. The coefficients are determined through the parametric study and it is found that the geometry of wide-flange steel is a dominant factor. The suggested models are applicable for square SRC columns with the size of wide-flange steel is over half of the total size of column. Comparison of the prediction with the experiment shows that the suggested models are quite reasonable. (C) 2018 Elsevier Ltd. All rights reserved.-
