The buckling-restrained braces(BRBs) with low yield strength(LYS) steel make good use of ductility and hysteretic energy dissipation of the low yield strength steel and are gradually applied in structural vibration. To foster BRBs with low yield strength steel in China mainland, the domestic LYS160 was used in BRB. The cross section was a simple shape. A static cyclic test was carried out, and the finite element analysis was conducted. The results show that the BRB with domestic low yield strength steel has good ductility, hysteretic energy dissipation and resistance to fatigue. A shaped cross section is simple and easy to promote application in China mainland.
