Following the previous investigations, this paper presents a further study on developing two kinds of high-performance seismic damper, namely Buckling Restrained Rippled Plate damper (BRRP) and Rippled Plate-Buckling Restrained Braces (RP-BRB). In order to facilitate the design process of BRRP/RP-BRB, the following three subjects are investigated: (1) the optimum proportioning of the rippled core plates, (2) the proper gap between the core plate and the restraining plates to avoid the so-called blocking phenomenon and (3) a simplified restoring force characteristics of the dampers.
