Composite structures can exhibit excellent performance against seismic force, and fire safety as well. However, the traditional steel reinforced concrete (SRC) system or concrete encased steel section system requires heavy labor and has shortcomings in its productivity. A new composite structural system was developed, aiming at improving its productivity. It is composed of concrete encased steel columns and composite beams. H-shaped steel columns and H-shaped steel beams are connected by high strength bolts using T-stubs. Strength of beam-to-column connections of this composite structure under seismic loading was investigated experimentally, and test results were compared with the theoretical prediction.
