Abstarct: In the recent years, efforts have been done to revitalize the force method. A new automated force method formulation known as the Integrated Force Method (IFM) has been developed by Patnaik. The independent forces are treated as unknown variables which are obtained using both the equilibrium equations and the compatibility conditions. Unlike the conventional Stiffness method or Displacement method (DM) where Stresses are calculated from the approximate differential of displacement, IFM applies Interpolation of forces. That is why this method is more accurate in the calculation of stress and requires less mesh density in the process of structural analysis. In addition, in the analysis of continuum the calculation speed is increased by reducing the number of elements. It has also been successfully extended to the free vibration and buckling analysis of the structures. Therefore, in this thesis the use of IFM in analyse of various structures has been investigated and a comparison between IFM and DM has been done. In this regard, the basic equations of finite element method IFM for the analysis of structures is presented. Finally, for investigating the proficiency of this method of analysis optimization of a truss structure and a concrete slab using Multi search Method and Simple Genetic Algorithm with different number of elements has been done to investigate the proficiency of this method of analysis
