1Stiffness method is used to study both statically determinate and indeterminate structures.It requires a different procedure to study both statically determinate and indeterminate structures.
2This method yields displacements and forces directly.In this method, the displacements are not obtained directly, so it requires some extra steps.
3In this, we determine the degree of kinematic indeterminacy(Dk).In this, we determine the degree of static indeterminacy(Ds).
4In this, we calculate reactions and moments.In this we calculate deflections and rotations.
5Also known as displacement method.Also known as force method.
6Ds > DkDs < Dk
