The authors propose an anti-symmetric Z-type NC braced frame as a new structural system for a seismic response reduction mechanism based on elastic energy accumulation capability produced by a wedge device. The previous paper described the seismic response reduction performance of a single-story braced frame due to elastic energy accumulation based on shaking table tests and actual-scale numerical analyses. The purpose of this paper is to expand this system to multi-story braced frames. Shaking table tests on two-story specimens are carried out to clarify basic performance, and numerical analyses are used to verify reappearance. Numerical analyses of actual-scale two-story braced frames are conducted to examine seismic response behavior and response reduction capability of multi-story braced frames.
