Abstract

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.
