A Review of Seismic Behavior of Circular Shallow Foundations Using PLAXIS

Abstract

This This paper presents a comprehensive review of the seismic behavior of circular shallow foundations, with a focus on the role of soil-structure interaction (SSI) under earthquake loading. Both experimental and numerical studies are examined, including large-scale shaking table tests, advanced finite element simulations using PLAXIS, and analytical models. Special attention is given to the effects of dynamic loads, liquefaction, bearing capacity, settlement, foundation uplift, and nonlinear soil behavior. Geogrid-reinforced soils and their potential in improving seismic performance are also discussed. The review highlights recent developments in SSI modeling, parametric studies on soil and footing properties, and the influence of ground motion characteristics. Limitations in current modeling approaches and gaps in experimental data are identified, suggesting directions for future research. The findings aim to support improved design methodologies for safer and more resilient foundation systems in seismic regions.
