OpenSees software was used to simulate a two-story three-span buckling restrained brace concrete frame (BRBCF) that adopts an anchoring connection joint with a T-stub, and the simulated results were compared with the test results to verify the accuracy of the model. The seismic behavior of the original BRBCF of the test frame was then analyzed. Good agreement between the numerical and experimental results was obtained, and OpenSees could accurately simulate the seismic performance of BRBCFs. The BRBCF showed good energy dissipation and horizontal bearing capacity, and the buckling restrained braced frame system revealed favorable seismic performance by increasing the lateral stiffness of the structural system and effectively controlling the deformation of the structure.
