Abstract:This paper presents a summary of experimental data on behavior of new and repaired structural walls. The data are applicable to walls used as lateral load resisting elements for wind or earthquake forces. Three approaches were used to repair damaged web concrete in test specimens. Performance of repaired walls based on measured load and deformation characteristics is described and compared to that observed for original specimens. Test results indicate that replacement of web concrete is a simple and effective repair procedure. Strengths of repaired wails were equivalent to those of original walls. Initial stiffnesses of the repaired walls were less than those of original walls. Increasing thickness of the repaired web improved inelastic response as did addition of diagonal reinforcement in the web.
