Abstract: As we know the foundation is the most important member of the building and a precise analysis of footing will results in more safe and economic design. In the present study combined rectangular footing loaded with both Axial force and Moment on both columns is analyzed using Rigid (conventional) Method and the same footing is also analyzed by Finite Element and Winkler Model Approach and the results of both analysis is compared. The results of an analysis typically include support reactions, Bending and shear stresses and displacements. The Winkler Model Method is sometimes also called as Simplified Elastic Approach. Further the Computer program is written in MATLab to solve the problem and parametric study is also carried out for various values of Number of Element, Modulus of Subgrade reaction (Kf).

Keywords: Combined Rectangular Footing, Finite Element Method, Simplified Elastic Approach
