Voimaemenetelmä
Voimaemenetelmä, often translated as the "force method" or "stiffness method" in English, is a fundamental concept in structural analysis used to determine the internal forces and displacements within a structure. It is one of the two primary approaches, alongside the displacement method, for solving indeterminate structures. The core idea behind the force method is to treat unknown support reactions or internal forces as redundants.
The process begins by identifying and releasing these redundant forces, transforming the original indeterminate structure into
The mathematical formulation of the force method often involves the use of flexibility coefficients, which relate
