Abstract

Recently, Buckling-restrained-braces (BRB) has been widely used in steel building frames as seismic energy dissipation members. In these braces, connections are designed as rigid in rotation for in-plane direction, while joint rotation subjected to story drift being absorbed by slight angle at the end of plastic area of core plate in restrain tube. On contrary, for out-of-plane direction, it is sometimes difficult to design connection as rigid in rotation, and three-hinge instability including connections and core-end hinges is concerned. If the brace member including connections becomes instable, BRB cannot fulfill its function as energy dissipation devices. In this paper, out-of-plane stiffness of various types of gusset-plate connections including bolted joint system are tested, and required conditions of the connections for stable BRB's action are analyzed and discussed.
