Abstract : Members of structure deform due to external loads. The minimum number of parameters required to uniquely describe the deformed shape of structure is called “Degree of Freedom”. Displacements and rotations at various points in structure are the parameters considered in describing the deformed shape of a structure. In framed structure the deformation at joints is first computed and then shape of deformed structure. Deformation at intermediate points on the structure is expressed in terms of end deformations. At supports the deformations corresponding to a reaction is zero. For example hinged support of a two dimensional system permits only rotation and translation along x and y directions are zero.
