One specmi en frame is for comparison and has no infilledwalls, and the other two frameshave infilledwalls, w ith either wt o bays infilledw ith half-heightwallor only one bay infilledw ith al-lheightwal.l Based on the test results, the damage characteristics, hysteretic curves, skeleton curves, displacement ductility, stiffness degradation, strength degradation and energy dissipation were analyzed. The results indicate that: Infill walls may enhance the lateral stiffness and strength of the frames; The configuration of infillwalls affects the failure modes of infilled RC frames, and all the columns connectingw ith infillwalls exhibit shear failure; Infillwalls have strong restraint effecton the frames, and as a result, the framew ith two-bayhalf-height infilledwalls underwent short column failure; As fortheRC framewith al-l height infilledwall in one bay, the infilledwall participated in the structural hysteretic energy dissipation. A lthough shear failureoccurred in those columns connectingw ith infillwalls, the frame stillexhibited hig
