The authors propose a Z-type NC braced frame with reduction capability of earthquake response in elastic region by elastic strain energy accumulation. The following conclusions were obtained from shaking table tests and numerical analyses of one-story NC braced frames. 1) Z-type NC braced frames characterize one-directional incremental deformation performance. 2) Earthquake responses of the elastic frames can be reduced by function of the energy accumulation. 3) The frames in plastic region show bi-linear-type restoring force characteristics and therefore they absorb equal level of plastic strain energy to BRB braced ones. In this paper shaking table tests of two-stories Z-type NC braced frames are carried out to examine these functions of multi-stories frames. The experimental results clarify the performance of one-story frames applying to multi-stories ones.
