This report summarizes the information obtained from static and dynamic tests of scale-model Seismic Category 1 structures (exclusive of containment) on the damping of low-aspect-ratio, reinforced concrete shear walls. The report reviews experimental assessments of damping in low-aspect-ratio shear walls that have been reported in the literature and presents a summary of the types of structures and structural elements tested. It discusses the testing methods and the methods used to determine equivalent viscous damping ratios (both directly and indirectly), a numerical study that examines the accuracy of various methods for estimating damping from measured acceleration input and response data, and tabulates the damping results. The report concludes by graphically showing the changes in the damping of the shear walls as a function of the peak nominal base shear stress experienced by the structure during simulated seismic events. Also included are comparisons of the damping results obtained in this program with those obtained by other investigators.
