Finite Element Analysis of Seismic Behavior of New Hybrid SCCC Composite Columns

In view of status that the new circular hybrid Steel-Concrete-CFRP-Concrete column (simply called SCCC columns) which was proposed by some scholars nearly tow years, hasn't made a deep research in seismic performance. In this paper, using finite element software ABAQUS simulate seismic behaviors of SCCC composite columns which under the action of axial compressive force and low cycle reversed loading, studied the effect on seismic performance of composite columns in different diameter CFRP tubes. Analysis results show that, along with the increase of CFRP tube diameter, the seismic performance of composite columns had different degrees of improvement. But see from the structure's fire behavior, the increse of CFRP tube diameter will make fire resistance time decreased obviously. Therefore, it is necessary to determine a suitable diameter scope, makes the composite column can play its performance. At the same time, can provide effective theoretical analysis method for experimental.
