This study proposed proposes a retrofitting method using an H‐beam frame to improve the seismic performance of non‐seismic designed reinforced concrete frames. To evaluate the seismic performance with the H‐beam frames, a cyclic lateral load test was performed and the experimental result was compared with the bared frame, and a masonry infilled RC frame. The results was were analyzed regarding aspects of the load‐displacement hysteresis behavior, effective stiffness, displacement ductility, and cumulative energy dissipation. AlsoIn addition, it was possible to prove both an increase of in the maximum load capacity, effective stiffness, and energy dissipation capacity using the H‐beam frame.
