The reinforced concrete slender walls are frequently used in moderate-to-high rise buildings to resist the lateral loads induced by earthquakes and to limit the building lateral drift by their lateral strength and stiffness. Current seismic design of reinforced concrete structures in the U.S. follows the provisions of Chapter 21 of the American Concrete Institute (ACI 318-11) building code requirements (ACI 318-11, 2011). The technology of seismic retrofitting using of slender walls had already developed in NCREE handbook. In the study, a simplified analytical method to estimate force-displacement response of a structural wall, utilizing the moment-curvature relationship, was proposed and validated by the experimental results from literatures. In addition, tests of shear wall are compared with the analyses of the strength of walls. Based on the obtained base shear – top displacement curve and failure mechanism, this study proposes some recommendations for design and analysis of slender walls.
