Abstract
In order to investigate the seismic performance of reinforced concrete frame with unequal span, a specimen was tested under low-cyclic loading and the seismic performance of this frame was analyzed based on fiber element method using software OpenSees. Hysteretic curves, skeleton curves, ductility, stiffness degradation and energy dissipating capacity of the frame are compared and analyzed. The experimental and simulate results demonstrate that this frame has a poor seismic performance. Thus, it is suggested that the seismic strengthening criteria of unequal-span frame structure should be raised and the existing buildings of this structure should be retrofitted.
