Engineers often face challenges when designing foundations that are located on top of or adjacent to slopes. The effect of eccentricity with the presence of weak layers adds to the complexity of the issue. In this research, using small-scale model tests, the effect of off-center loading on the bearing capacity of the strip foundation adjacent to the sloping multi-layer gable with a weak soil layer has been investigated. Thin layers have significant effects on the ultimate load-bearing capacity, despite their seeming insignificance. A series of laboratory model tests were conducted on a rigid strip footing placed on surfaces with different layered slope footings. The test program considered different foundation configurations by varying the distance of the footing from the crest of the slope and the slope of the thin layer. It is found that the weak thin layer reduces the ultimate bearing capacity. The laboratory results show that the amount of eccentricity affects the final bearing capacity of the foundation and increases the bearing capacity by moving away from the weak layer and the crest of the slope. The weak thin layer at the critical distance D = 0 leads to a further reduction of the final bearing capacity by 43%.
