Results of 37 tests or moderate-rise structural walls subjected to lateral loads are reviewed. Lightly reinforced walls with low axial stresses are found to be vulnerable to failure caused by fracture of the main reinforcement. In some cases, failure was observed at low lateral drift ratios. Two approaches are presented to identify during the design process those walls that are susceptible to fracture of the reinforcement.
