Abstract: High-level testing of large civil structures is usually not practical, due to structural damage considerations and available testing equipment. However, in the case of a joint American/German research effort, both of these issues have been resolved. In order to test a nuclear power plant containment structure to response levels of approximately 1. 0 g, a 2-kiloton eccentric mass vibrator has been designed and built. It will be used in early 1986 to test the containment structure to obtain data on soil-structure interaction and nonlinear response. Simulations have been performed to predict structural response and shaker performance. Included in this paper are vibrator design specifics, anchorage description, and simulation results.
