The clearance of the buckling-restrained brace is a factor that has a significant influence on its failure mode and mechanical behavior. In this study, the clearance adjustment construction for the buckling-restrained brace using steel mortar planks is improved. Further, the clearance adjustment construction of partially pasting fluororesin sheets or butyl rubbers to a core plate or spacers is proposed. The requirements for workability, cost performance, reliability for fabrication, and structural performance for safety is examined. Finally, based on a comprehensive evaluation, it is verified that the practicality of the proposed clearance adjustment construction.
