The Moment-Curvature Relation of SRC Column Based on the Fiber Model Method and its Influencial Factors Analysis

Because the SRC (steel reinforced concrete) structures fully combine the advantages of two materials i.e. steel and concrete they had been widely used in high-rise buildings. Completely study the moment-curvature relation of this kind of member is essential to a nonlinear analysis of this type of structures. The fiber model method based on the section discretion directly reflect the restoring characteristics of the member though the stress-strain relationship of steel and concrete. It can be applied to analyze section with any configuration. In this paper, the hysteretic moment-curvature relation of SRC column is analyzed by coding and verified by available test result. And finally several factors influenced on the M-Фrelation is discussed.
