Big cities are growing quickly, and that means there's not enough space for constructing new structures. Despite unfavorable building conditions, multi-story structures are being constructed on the slopes of hills in considerable numbers in the hilly regions of northern India. The structure's load transferred through its foundations that elevates shear stress on the slope which potentially leads to instability of hill slope if shear stress exceeds shear strength. Interface between footing and slope and location of foundation on slope are the key parameters which affect the static and seismic stability of slopes. Most of the previous studies discussed the seismic analysis of footings at the top or crest of the slope. But limited research was carried out for seismic analysis of foundations located at the surface of slope. In this paper, static and seismic analysis of single and multiple adjacent footings on the surface of slope has been carried out. The finite element method was employed for the analysis using PLAXIS software. The impact of interactions between adjacent footings and soil slope has also been studied. The study also examined the effect of the width of footing, edge distance of footing from the surface of slope, and distance of footing from the top of slope. The response has been found out in terms of factor of safety, displacement, bearing capacity, and induced acceleration. It has been revealed that slope stability and settlement of footing were affected by interface between footing and soil slope, location of footing and width of footing under the static and earthquake loadings. Further maximum response of footings on slope has been obtained for a typical combination of width of footing, edge distance of footing from surface of slope, depth of footing on top of slope, and interface factor between footing and soil slope.
