Abstract：In order to study aseismic performance of a steel-concrete combined frame in imitated ancient buildings, a steel-concrete combined frame of a hall type imitated ancient building in the zone with an aseismic fortification intensity of 7 was taken as the original type to design a 1∶2 scale steel-concrete combined frame.The quasi-dynamic tests were conducted for the designed frame.The earthquake waves including El Centro wave, Taft one and Lanzhou one were inputted，respectively and the peak ground acceleration were 35 gal (7 frequently occurred earthquake), 100 gal (7 fortification earthquake), 220 gal (7 rare earthquake) and 400 gal, respectively.The frame’s acceleration time history curves, base shear-displacement hysteretic ones, energy dissipation capacity and deformation performance were measured.It was shown that the designed steel-concrete combined frame has better plastic deformation performance; the frame’s natural frequencies and dynamic amplification factors decrease with increase in earthquake acceleration; when the peak acceleration is 400 gal, the structure stiffness decreases 66% compared with that when the peak acceleration is 35 gal; its energy dissipation capacity increases with increase in earthquake acceleration; this capacity varying amplitude is different under different seismic waves, it is the largest under El Centro wave, and it is the smallest under Lanzhou wave; the frame can meet 7 aseismic fortification requirements, and it has a good aseismic performance.
