Abstract:

Steel frame and energy-saving composite panel can be connected in specified arrangements to form a coordinating structural system, which has the good property of lateral resistance. In order to study different effects of lateral resistance and hysteresis characteristic between two arrangements, two full-scale models with a conducting low-cycle reciprocating loading test were designed, which were called beam connection and column connection. It was proved that both systems could effectively improve the ultimate bearing capacity and lateral stiffness. Compared with the beam connection, the column connection showed a better ductility, energy dissipation, structural integrity and reliability. In addition, the column connection could give better seismic performance than the beam connection.

Key words: energy-saving composite panels, steel frames, beam connection, column connection; , hysteretic behavior
