A Simplified Method for Seismic Fragility Analysis of Geogrid-Encased Stone Column Composite Foundations

This study proposes a machine learning-based probabilistic framework to analyze the seismic fragility of geogrid-encased stone column foundations, revealing that native soil shear strength and vertical seismic coefficients are the most critical factors influencing failure probability and guiding design toward high-strength geogrids, adequate footing width, and high area replacement ratios.
