In the nuclear power plant Krško (NEK) the seismic resistance is continuously checked by taking into account the latest available data and modern methods of analysis. The research team at FGG, involved in earthquake engineering, has successfully collaborated with the NPP Krško for many years, especially in reviewing and assessing projects that are related to the seismic safety of NPP facilities and their equipment. The report contains the results of an independent evaluation of a project, conducted by a U.S. company, comprising the determination of floor spectra for all objects of the nuclear island at increased seismic loading (maximum ground acceleration of 0.6g). In the review, we developed, independently of the contractors, the mathematical model of the buildings of the nuclear island and conducted several independent control analyzes. Our work was facilitated by the knowledge gained in the research of floor spectra.
F.17 Transfer of existing technologies, know-how, methods and procedures into practice
COBISS.SI-ID: 6465377In the EU Seventh Framework Programme (FP7) the research project Seismic engineering research infrastructures for European synergies (SERIES) was carried out in the period 2009-2013 (SERIES, http://www.series.upatras.gr). 23 partners, including all major infrastructures in Europe and three industrial beneficiaries, were involved. The project offered to the European earthquake engineering research community and industry an opportunity to access large-scale research infrastructures. Within the project, a task was devoted to the development of a database of existing tests on reinforced concrete (RC) structural elements. The database has been assembled from existing experimental data from literature, to provide researchers with the data needed to evaluate and develop seismic performance models for different RC load bearing elements. The database includes data on RC walls, columns and beams.
F.15 Development of a new information system/databases
COBISS.SI-ID: 6467169Within the project POTROG some professional bases and tools have been prepared for a significant upgrade of existing system for comprehensive earthquake preparedness. The existing and new estimates of seismic resistance and vulnerability of individual buildings (database ZAG) have been entered into the updated database, which has been connected with other publicly available databases. Individually, 155 different buildings have been assessed. Some reasonable correlations have been estimated for different structural types (stone and brick masonry, reinforced concrete, steel and mixed) between seismic vulnerability and basic data about the year of construction and the number of storeys. Based on these correlations the seismic vulnerability and seismic resistance of all building in the areas of Slovenia under consideration have been estimated. A risk assessment model for buildings has been prepared. Earthquake damage and usability form has been upgraded. An application for the automatic prefilling of forms has been prepared. It will provide a more efficient fulfillment of forms in field on one hand and a faster data entering and evaluation of earthquake effects in the information center on the other hand. Safety instructions and web educational contents for citizens have been developed. Leaflets for households and children, a poster for children and a detailed brochure with earthquake safety instructions have been prepared upon an extensive review of available educational materials. A standalone internet application that has been prepared for general public allows an individual to estimate the expected damage of his building in case of earthquake.
