In this paper,a static nonlinear analysis of SRC frame has been made,and the analytical results agree well with those of the tests. In the same parameter settings,the static nonlinear analysis of a 2-span,3story SRC column-steel beam hybrid frame is then carried out to learn its seismic performance when the steelratio of SRC column and linear stiffiness ratio of beam to column is different.The results show that the bottomstory of SRC column-steel beam hybrid frame achieve the strong column-weak beam failure mode,so the overall structure experienced a long plastic deformation stage and exhibited good ductility. With the increase of thelinear stiffness ratio of beam to column,the failure of hybrid frame gradually turned from the overall"strongcolumn-weak beam”mode into "strong beam-weak column"mode, and the structure ductility reduced Significantly.According to the calculation results,a reference value range 0.3 ~0.4 is suggested for line stiffnessratio of beam to column in SRC column-steel beam hybrid frame design.
