| Abstract |
The analysis method proposed by Fintel et al. is widely used in calculating the column shortening of reinforced columns. However, the predicted shortening showed significant difference from the measured shortening in case of composite column. The differential drying shrinkage of concrete column section was investigated based on moisture diffusion of concrete to enhance the accuracy of column shortening of composite columns. The simple modification factor is proposed to consider blockage effect of steel section to moisture diffusion in composite column. |
