Besides the variation of earthquake inputs, the inelastic characteristics of structures themselves are also the influence factors on the seismic response dispersion of structures, in which the post-yielding stiffness is key parameters. In this paper the inelastic time-history analysis of numbers of SDOF and MDOF systems are studied to investigate the influence of post-yielding stiffness on the inelastic seismic response and the dispersion. The analytical results show that, (1) for SDOF system, the larger positive post-yielding stiffness will result in smaller the maximum displacement and especially the residual displacement, (2) for the MDOF system, the larger positive post-yielding stiffness results in more uniform distribution of hysteresis energy dissipation and the smaller variation of the maximum inelastic story drift. Hence, the larger of the positive post-yielding stiffness will result in a better control of structural performance under earthquake, so that the performance based design can be easier implementation. The methods to increase the post-yielding stiffness and some practical examples are finally presented in this paper.
