In structural engineering, the matrix stiffness method (or simply stiffness method, also known as Direct stiffness method) is a matrix method that makes use of the members' stiffness relations for computing member forces and displacements in structures. For example, if k is the stiffness of a spring that is subject to a force Q, the spring's stiffness relation is:
where q is the spring deformation. This relation gives q = Q/k as the resulting spring deformation.
