Abstract -Each foundation should provide a sufficient margin of safety against the greatest loading that it might withstand, even if this loading only occurs occasionally throughout the structure's lifetime. That is to say, an excessive burden or an incorrect assessment of the soil's qualities should only increase settling. PLAXIS is a finite element programme designed primarily for the investigation of deformation and stability in geotechnical engineering applications. The expanded output tools offer a detailed presentation of the computational findings, and the graphical input processes enable speedy production of complex finite element models. The computations are entirely automated and grounded in reliable numerical techniques. An accurate understanding of the load-settlement behaviour of the various types of soil beneath the footing is essential for foundation design. The major goal of this work is to use PLAXIS 2D to analyse the load-settlement behaviour of circular footings lying on soil mediums covering different types of soils. To do this, five models of various soil types bearing axial, inclined, and eccentric loads are taken into consideration. Each case's failure loads are noted, and comparisons for load-settlement are made for these soils. PLAXIS-2D.v.8.2 is the programme used for modelling and analysis. A 2d FEM analysis was conducted on rectangular and square footing carrying axial loads from an analytical research and compared with the results of the PLAXIS-2D analysis in order to validate the suggested model.
