Pseudo-dynamic tests were performed on a one-seventh scaled specimen to investigate the that was subjected to the El-Centro NS wave. The tested specimen with steel reinforced concrete (SRC) frame and reinforced concrete (RC) wing-walls was designed for industrial buildings in thermal and nuclear power plants. Due to special requirements from facility installation, beam-column connections were designed with inevitable strong-beam weak-column mechanism, wing walls aim to primarily dissipate hysteretic energy and postpone the damage and collapse the frame. Test results indicates that the specimen demonstrated dual seismic-resisting mechanism under severe earthquakes with PGA=3.0 g which is beyond the code requirement of with the return period 2 % in 50 years. A region of drift concentration was found in the range of 2.40~4.80 m. Various primary story levels of the specimen showed difference in lateral stiffness, which is consistent with the contribution ratios of the cumulative hysteretic energy. The first and second primary stories dissipated most of the input hysteretic energy. This hybrid structural system is anticipated to provide high ductility as industrial buildings in seismic prone regions.
