Structural analysis of statically determinant structures is the foundation of understanding Structural Mechanics. Therefore this course forms the basis in Civil Engineering studies and the forthcoming professional career. The course offers a systematic study the internal forces and deformations of structural systems, the behavior of which is governed by the equilibrium, which is the most fundamental principle of Engineering.
