Survival analysis of a liquefiable embankment subjected to sequential earthquakes

In practice, the performance of structure is studied based on a seismic scenario composed independent single earthquakes. But in real life, subjected to multiple earthquakes during its typical design working which will produce an evolution damage with time.The main purpose this paper quantify liquefaction-induced embankment due sequential defined life. Moreover, non-parametric survival analysis used estimate time (in years) until level reached specific interval. For purpose, site was chosen where seismicity and Probabilistic Seismic Hazard Analysis (PSHA) were identified. First, site-specific assessed, that consists finding relation between Intensity Measures (IM) Engineering Demand Parameter (EDP). Second, order lifetime distribution as well Mean Time To Failure (MTTF) embankment, functions drawn. The histories stochastically generated from synthetic ground motion models. study, elastoplastic multi-mechanism soil behavior model used.According obtained results, after loading, cumulative either progressive or without extensive damages sudden drastic damages. model, reaches moderate before addition, numerical parametric performed impact considering (or not) loading history recovery each MTTF embankment. This study pointed out importance since it affects overall Finally, two models assessed generalize, certain extent, work.
