Abstract
The prediction of Concrete Filled in steel Tube(CFT) column shortening, causing serviceability problem and additional stresses in horizontal structural members, is of fundamental importance.

According to the available study and experimental data about the long term behavior of CFT columns, the creep and shrinkage of concrete in CFT columns are smaller than those of RC columns because of the confinement effect of outer steel columns.

In this study, the uncertainties associated with assumed values for concrete properties such as strength, creep coefficients, and load have been considered and analyzed for the prediction of time-dependent column shortening of CFT column.

The CFT column shortening analysis using Monte Carlo method is proposed and an example of a 37 story tall building with CFT columns is studied for illustration.
