Abstract
When steel and concrete composite structures are designed by using the limit state design method based on the reliability analysis, it is required to obtain appropriate resistance factors for members in the structures. The purpose of this paper is to obtain resistance factors for two types of composite columns on the ultimate state. One of the types is steel reinforced concrete columns and the other concrete-filled tubular columns. The resistance factors are determined by considering probabilistic properties for both member strengths and applied loads including seismic forces. Therefore, the load factors for the composite columns are also discussed in the paper.
