Abstract: The static elastic-plastic analysis of a four-story two-bay Self-centering Steel Moment-resisting Plane Frame( SC-MRFs) are conducted by FEA software ABAQUS,and three SC-MRFs with different steel strength of Q345,Q420 and Q460 are calculated.The seismic performance of SC- MRFs and the effect of steel strength on self-centering capability are discussed.The results indicate that the increment of steel strength has an obvious effect on decrement of structural plasticity and residual drift,but it can’t completely avoid the plasticity of column bottom.Besides,it also affects connection relative rotation to some degree and friction energy dissipation,but has little influence on the loss of prestressing steel strand.
