CHALLENGES FACED DURING THE MODELLING, DYNAMIC ANALYSIS, AND VULNERABILITY STUDY WITH SOFISTIK IN THE CONTEXT OF THE SMART 2013 BENCHMARK PROJECT

摘要

The international benchmark project SMART 2013 that has been supported by CEA and EDF under the hospice of the IAEA aims at understanding the nonlinear response of a typical nuclear reinforced concrete (RC) structure subjected to high intensity seismic loading. An experimental campaign on a new mock-up, which has been launched in 2013 and has been carried out at Centre de Saclay/EMSI, provided reference data for the project. This paper describes the work conducted by the "ENSI Team 2", consisting of the Swiss Federal Nuclear Safety Inspectorate (ENSI) and the Stangenberg & Partner Consulting Engineers (SP1), in the context of the benchmark project. The paper focuses on the challenges faced during the modelling procedure, on the findings gained from the comparison between the accelerations and displacements predicted by the numerical model and the measured experimental results, and the vulnerability study with establishing of different fragility curves.
