Comparison Between Frequency Response Analysis and Computational Fluid Analysis in Sloshing Evaluation

Abstract

This study presents a simplified method for analyzing pool sloshing during earthquakes, using frequency response analysis. It starts with a linear formula for water surface movement, extends it to include damping effects, and derives response functions for water level and pressure. By comparing with numerical fluid analysis, the study confirms the accuracy of this approach in calculating sloshing for different acceleration inputs. This method offers a convenient alternative to complex simulations for studying pool sloshing behavior during earthquakes.
