Date: 5/1/1984. Abstract: Results of an experimental investigation of isolated reinforced concrete structural walls subjected to inelastic load reversals are discussed and evaluated. Walls subjected to significant inelastic deformations and with strengths limited by concrete crushing of the web after flexural yielding are considered in this paper.
