摘要

The Collaborative Research Center 461 (CRC 461) Strong Earthquakes: A Challenge for Geosciences and Civil Engineering (Germany) and the Romanian Group for Strong Vrancea Earthquakes (RGVE) work on a multidisciplinary attempt towards the mitigation of the impact of the next strong Vrancea earthquake (Romania). The recently installed Multidisciplinary Seismic Test Site INCERC (MSTS) located in the eastern part of Bucharest serves as focus to study the entire sequence relevant in engineering seismology including structural dynamics, seismology, soil mechanics, and engineering geology. Within this co-operation, the complete chain for seismic hazard and seismic risk analysis and can be checked and verified. For this purpose a base isolated test building was constructed, where acceleration will be measured at the base and at the top. Additionally, free field accelerometers in various depths were installed. Thus, free field accelerations and the response of the test building can be measured simultaneously. One of mainly objectives, among others, is to investigate the complete dynamic system, incorporating the base isolated test building and the soil, under seismic loading. Geotechnical parameters which will be available to a depth of 180 m ensure that the soil response incorporating the seismic behaviour of rubber bearings can be computationally studied with Finite Element methods (FEM). These simulations include constitutive laws describing non-linear behaviour of rubber and soil material under cyclic loading.
