Method of Analysis

Structural analysis is based on Finite Element Method. Stiffness properties of elements are derived using finite element formulation. Stiffness properties are evaluated accurately for the static loading and linear stress-strain relations. Beam, column and trussbar elements are connected via nodes. All external loads having 6-force components are acting inspace of 3-dimensional structure.
