In the recent past years, utilization of intelligent models for solving geotechnical problems has received considerable attention. This paper highlights the feasibility of adaptive neuro-fuzzy inference system (ANFIS) for predicting the bearing capacity of thin-walled foundations. For this reason, a dataset comprising nearly 150 recorded cases of footing load tests was compiled from literature. Footing width, wall length to footing width ratio, internal friction angle and unit weight of soil were set as inputs of the predictive model of bearing capacity. Additionally, a pre-developed artificial neural network (ANN) model was constructed to estimate the bearing capacity of thin-walled foundations. The results recommend the workability of ANFIS in predicting the bearing capacity of thin-walled foundation. The coefficient of determination (R2) results of 0.933 and 0.875, and root mean square error (RMSE) results of 0.075 and 0.048 for training and testing datasets show higher accuracy and efficiency level of ANFIS in estimating bearing capacity of thin-walled spread foundations compared to ANN model (R2 = 0.710, RMSE = 0.512 for train, R2 = 0.420, RMSE = 0.529 for test). This study suggests utilization of ANFIS, as a feasible and quick tool, for predicting the bearing capacity of thin-walled spread foundations; though further study is still recommended to enhance the reliability of the proposed model.
