This paper reports cyclic loading test results of three one-story, one-bay reinforced concrete moment resisting frame specimens. Two of the specimens have secondary walls which are monolithically constructed or structurally isolated by seismic slits. Consequently, the isolated wall as well as monolithic wall increased the strength of moment resisting frame. This was caused by a small amount of tie bars which were provided for the isolated wall at the wall/frame boundaries. Therefore, a calculation procedure is presented based on the principle of virtual work mainly to evaluate the lateral strength of moment resisting frame with the isolated wall.
