Structural Analysis is the branch which involves in the determination of behaviour of structures such as Buildings, Bridges, Dams, Towers, Offshore Platforms, Retaining Walls,
Truss Foundations and Stadiums. The concepts of Statics provide basis for solutions to the structures. Computer software are also being used for the calculation of forces, bending moment, stress, strain and deformation or deflection for complex structural systems. Sophisticated
are also used for investigating the structural response under different types of loading. Basic concepts of are essential before structural analysis. Structural analysis provides the basis for structural design. A structure can be statically determinate or Statically determinate structure. A structure is termed as statically determinate if all of its unknown forces can be determined by using only the equations of static equilibrium.
