In order to study the seismic performance of fully bolted semi-rigid eccentrically braced steel frame, a pseudo-static loading test was carried out on a single-story single-span eccentrically braced steel frame. The seismic behavior of the specimen has been analyzed according to the failure mode, hysteresis curve, bearing capacity, ductility, energy dissipation performance, and stiffness degeneration etc. The experiment results show that this structural system has fairly good energy dissipation capacity, strong bearing capacity and excellent ductility. Except for the link, other members of the frame are in the elastic stage, indicating that the specimen is easy to repair after earthquake. The hysteresis curve of the specimen shows significant pinch phenomenon owing to the slip of the bolt.
