The values of displacement in {D} necessary to ensure the equilibrium of the joints are determined using the relation (displacement vector = {D}; stiffness matrix = [K]; and load vector = {P}

In the flexibility matrix method of analysis, the values of redundant forces necessary to ensure geometric continuity of structure are determined by using relation (displacement at release due to applied loading = D_p; flexibility matrix = F; redundant forces on released structure = X_R)

A three-span continuous beam is fixed at the ends and supported by unyielding roller supports in between. What is the size of the stiffness matrix?

For the structure shown, the elements of the flexibility matrix are
