Validation of a numerical model of a seismically isolated, cylindrical, fluid‐filled vessel
Numerical models capable of generating robust estimates of isolation‐system and fluid‐structure responses for multidirectional, high‐intensity shaking will be required for analysis, design, and risk assessment of seismically isolated advanced reactors. None of the few studies to date on base‐isolated, fluid‐filled vessels have generated datasets suitable for formal validation of numerical models. Earthquake‐simulator experiments on a fluid‐filled, cylindrical vessel, base isolated using four single concave friction pendulum bearings (SFP isolators) were performed. The dataset was used to validate a numerical model for high intensity, multidirectional seismic inputs. Fluid and isolation‐system responses obtained from analysis of the numerical model were in excellent agreement with experimental results. The numerical models and outcomes from the experiments are broadly applicable to base‐isolated, fluid‐filled vessels, regardless of industry sector.
