In the modern era, increasing trends of traffic is the major issue in all the urban cities. An adequate and efficient transport system is a pre-requisite for sustainable economic development. The increased traffic volume causes road congestion near rotary intersection. Road width (number of lanes) cannot be increased due to scarcity of land and thus elevated road or bypass road is only the solution. Elevated roads from different directions crossing each other require elevated rotary intersection. Elevated rotary requires strong and stable foundation to support dead load and traffic loads. In such cases, double ring foundation can be adopted to support the elevated rotary. In the present study, double concentric ring foundation has been studied for the different vertical loads and gaps between inner and outer ring foundations keeping ring radii ratio 0.4 using ANSYS. The minimum gap has been found as 0.55 times the outer diameter of the inner ring, while applying load on both inner and outer ring foundations. Parametric optimization has been also carried out using ANSYS. The effect of the number of columns (8, 12, 16) has been also performed. Sensitivity analysis of parameters has also been carried out using Python code, and it indicated that the outer diameter of ring foundation has the highest impact on settlement in comparison to other input parameters.
