ABSTRACT
Cyclic loading tests on three full-scale one storey,one-bay test specimens were carried out to study the hysteretic behavior of steel frames infilled with composite panels. The influential parameter taken into consideration is the connecting method of panel to steel frame. Based on the experimental phenomena, seismic behaviours of specimens are reflected by hysterics loops, skeleton curves, curves of strength degradation, and curves of stiffness degradation, ductility coefficient and equivalent damping coefficient. Test results show that the failure modes of panels and steel frames are concrete spalling around the embedded parts, and weld fracture and local buckling of beam respectively. The integrity of the panel is better than the traditional walls. The success of connection between panel and steel frame is significant to the mutual work of the two parts. By strengthening the connection can improve the seismic behavior of structure. At the end of the paper, seismic design recommendations based on the analysis of ductility index and energy dissipation of the structures are presented.
