This study is focused on the performance evaluation of the Y-Shaped knee braced frames with various friction and buckling mechanisms. Responses of framed structures under SAC Near-Fault protocol were compared with those of frames subject to SAC loading protocol to validate the effectiveness of the proposed Y-braced frame designs. According to the experimental results, the Y-braced frames could maintain the elastic stage within 1.8% drift ratio under the initial impact of the Near-Fault. It is also shown that the force of the beam-column joints was effectively reduced and the occurrence of plastic hinges was also delayed. Comparisons of test results validated the applicability of Y-braced frames to the seismic designs.
