Abstract
The authors conceived a buckling-restrained brace providing stable hysteretic characteristic even under high-strain conditions. In the past paper, conducting cyclically static loading tests, the performance evaluation formula of the buckling-restrained brace was presented. The many buckling-restrained braces in practical uses have weldings in the energy absorption area of the core plate. Brittle fracture might be caused, when the welding exists. In this case, the performance of the buckling-restrained brace decreases. In this paper, the specimens with different welding specifications and steel kinds are fabricated. Tensile loading tests are conducted as parameter of temperature. The tensile performance of the specimens with local welding and without welding is almost the same. The other hand, the performance of the specimens with continuous welding reduces.
