A brace that has a stable forth-deflection characteristic and enables compressive yield strength to be equal to tensile yield strength was developed around 1980 in Japan. A core steel plate is jacketed by the concrete encased in a steel tube to restrain buckling and coating materials are used between the concrete and the core plate to prevent the transmission of axial forces. More than 20 years have passed and the buckling restrained braces have been studied in many countries and used practically for many buildings. Based on a rational seismic design theory, the roots of the buckling restrained braces and the current developments for steel structures are discussed.
