Within a building, anchors are essential for the connection of various nonstructural systems to reinforced concrete elements, including shear walls. During an earthquake, anchors in reinforced concrete shear walls need to retain strength and stiffness, despite the presence of cracks, which develop during lateral cyclic loading. To investigate the behavior of post-installed anchors in walls that develop shear-flexural cracks, a slender full-scale wall is designed and constructed according to current U.S. design codes. Seismic loading was imposed on the wall through an equivalent cyclic displacement history applied at the wall top. The specimen failed in flexure, precipitated by buckling and fracture of the boundary reinforcement. The local and global response of this full-scale specimen is documented herein, with particular emphasis on the evolution of cracking. Such cracks result in boundary conditions to the anchors, whose behavior is discussed in a companion paper.
