In order to investigate effects of reinforcement detailing, slenderness and loading history on the capacity and failure modes of confined boundary regions of RC rectangular structural walls, eight RC rectangular element specimens were tested under monotonic and cyclic reversal loadings. It was found that the tensile strain prior to compressive strain affected the failure mode and maximum capacity of thin wall boundaries.
