Analyse sismique du comportement d'une structure de 7 étages à échelle 1 en béton armé : benchmark international NEES

The University of California at San Diego (UCSD), the Portland Cement Association (PCA) of Skokie, IL., and the NEES Consortium Inc (NEESinc) have performed a seismic research project around an uniaxial shaking table test on a mock-up representing a full-scale vertical slice of a seven-story reinforced concrete wall building. It is composed of two perpendicular walls linked with slotted connections. It was designed using a displacement-based and capacity approach for a site in Los Angeles. Multifiber Timoshenko beam elements are used to reproduce numerically the experimental behavior of the structure. It is shown that the modeling strategy describes accurately the global behavior of the structure and qualitatively the distribution of damage at the base of the specimen (even though the prediction is “blind”).
