Abstract In this paper the influence of nonlinear behaviour primary structure on floor spectra is investigated by means simple models. The general trends for different types one degree freedom (1DOF) are shown and we point out their common futures differences. A special attention given to cases elastoplastic elastic behaviours methods determine an equivalent linear oscillator proposed. properties (frequency damping) quite from oscillators commonly considered in practice. particular, case...
Summary The present work investigates the influence of small geometrical defects on behavior slender rigid blocks. A comprehensive experimental campaign was carried out one shake tables CEA/Saclay in France. tested model a massive steel block with standard manufacturing quality. Release, free oscillations tests as well table revealed non‐negligible out‐of‐plane motion even case apparently plane initial conditions or excitations. This exhibits highly reproducible part for short duration that...
One of the key elements probabilistic seismic risk assessment studies is fragility curve, which represents conditional probability failure a mechanical structure for given scalar measure derived from ground motion. For many structures interest, estimating these curves daunting task because limited amount data available; only binary in our framework, i.e., describing as being or non-failure state. A large number methods described literature tackle this challenging framework through parametric...
Seismic fragility curves are key quantities of the Probabilistic Risk Assessment studies carried out on industrial facilities.They express probability failure a mechanical structure conditional to scalar value derived from seismic ground motion called Intensity Measure (IM).Estimating such is daunting task because for most structures interest few data available.For this reason, some methods literature rely use parametric log-normal model coupled with Bayesian approaches parameter...
Fragility curves which express the failure probability of a structure, or critical components, as function loading intensity measure are nowadays widely used (i) in Seismic Probabilistic Risk Assessment studies, (ii) to evaluate impact construction details on structural performance installations under seismic excitations other sources such wind. To avoid use parametric models lognormal model estimate fragility from reduced number numerical calculations, methodology based Support Vector...
