Abstract
The experimental study on precast Concrete Encased Steel (CES) columns is outlined and the structural performance of the precast CES columns is discussed in this paper. The precast CES columns are constructed by connecting precast CES elements using bolts and fiber reinforced mortor. Fiver reinforced concrete is used for the precast CES elements. The purpose of this study is to obtain fundamental data on the structural performance and to construct analytical models of the precast CES columns applicable to pushover analysis used in the Calculation of Response and Limit Strength (CRLS).
The results showed that the flexural strength of the precast CES columns is developed by the yielding of their steel and the lateral deformation capacity is about 0.05 rad. in the story drift angle. The shear versus lateral displacement response of the precast CES columns is simulated by the Takeda model.
