Book Description
The objective of this study was to develop improved understanding of the seismic behavior of a lightly reinforced concrete (LRC) slab-column structure seismically retrofitted with viscoelastic dampers (VEDs). The feasibility of using VEDs to rehabilitate existing LRC slab-column structures was explored, and implications for structural design were considered. A model of a section of a 1950s-era three-story military barracks building was fabricated for testing. A rehabilitation scheme using VEDs was designed and implemented. This section model was subjected to a series of earthquake simulations on the shaking table at the U.S. Army Construction Engineering Research Laboratories (CERL). Experimental measurements included floor and VED displacements, floor accelerations, VED forces, and reinforcement strains. The earthquake simulations comprised a series of gradually increasing intensity replications of two commonly used earthquake records, first on the frame fitted with VEDs, then on the frame without VEDs. Interpretations of the testing results are provided through the use of linear models of the type that might be used in the design office. These analytical models also were used to assess the applicability of the linear modeling procedures that have been recommended in Federal Emergency Management Agency document 273, "NEHRP Guidelines for the Seismic Rehabilitation of Buildings."
