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, trussbar and plain stress elements are connected via nodes. All external loads are acting along the plane of 2-dimensional structure.
