摘要

Footings are an important part of building foundations, helping to transfer the weight of the structure to the ground. However, when footings subjected to eccentric loading, they can settle unevenly and tilt, which may weaken the structure. Traditional methods like combined and strap footings can help reduce this tilt, but they often complicate the construction process. This study suggests a new method using isolated footings with an added insertion to better handle eccentric loads. By adjusting the depth of the insertion, the goal is to reduce the tilt and make the footing more stable. The research uses Finite Element Analysis (FEA) to simulate different load conditions and test how these changes affect the footing’s performance. The results show that increasing the insertion depth can significantly reduce tilt, keeping the footing safe according to the IS 1904–2021 standards. This new approach offers a simpler and more effective way to handle eccentric loading, making foundation designs safer and more efficient.
