Paper Title:
The Experimental Study on the Effect of Expansive Agent on Mechanical Properties of CFST Column with the Creep
  Abstract

In order to study the influence of expansive agent on the performance of CFST column with the creep due to dead load of the practical construction, in this paper, based on the simulation phase of construction, a series of experiments were conducted to study effect of the expansive agent dosage on the ultimate bearing capacity of CFST columns and the creep deformation in the longitudinal direction. Also the experiments were completed to comparative study on the problem of the recycled aggregate concrete -filled steel tube (RACFST) column. It is found that the ultimate bearing capacity of the CFST column is increased a lot when using the expansive agent, while for the RACFST column it has just a little increase. In contrast, for the RACFST column, there is a greatly increase on the creep deformation in the longitudinal direction, and the more expansive agent dosage the larger deformation, but it is not so obvious effect for general CFST column.
