| Popis: | [EN] Assessing the probability of failure of a structure under seismic loading requires the simulation of a great number of similar nonlinear computations. A model-order reduction strategy is proposed for decreasing the computational cost associated to each nonlinear simulation. In this contribution, the method is illustrated to evaluate the damage evolution in a primary circuit piping component of a pressurized water reactor, subjected to accidental seismic input. Piping components are described with a damageable elasto-plastic material exhibiting a preliminary damage pattern. The SEISM Institute is deeply acknowledged for funding this research activity. This work is hosted by the NARSIS Project that is also thanked for giving the opportunity to study such thematic. |
