The goal was to evaluate the hysteresis performance of segmented buckling resistant braces with low yield point steel LYP160, the monotonic tensile and cyclic loading tests of LYP160 were conducted and the corresponding laws have been obtained. According to the load-displacement curves of the specimen, the low yield point steel was characterized by good ductility and energy absorption ability. With the consideration of Chaboche model on the materials, the cyclic loading was simulated by ABAQUS and the cyclic hardening parameters of low yield point steel were obtained. On this basis, the hysteretic properties of buckling resistant braces under cyclic loads were simulated and analyzed. After the analysis and comparison of buckling resistant braces specimens with isotropic core plate and segmented variable section core plate, it can be found that: When the buckling resistant braces with isotropic core plate was loaded to L/100, the lateral deformation of BRB would reach 17mm and the seriously squeezed would observe on lateral constraint members. The buckling resistant braces would fail due to the accumulation of deformation on lateral constraint members at both ends of BRB. When the segmented buckling resistant braces was applied, the core plate with variable section would yield first in the middle part, other parts could still continue to consume energy due to the action of the limit plate. It would avoid the phenomenon that other parts could not continue to consume energy after the core plate failed at one point first. Under the action of cyclic loads, the stiffness of the segmented buckling resistant brace was constant and the better ability to consume energy was reflected.
