Lattice Systems: Structural Equilibrium

This lecture covers the concept of lattice systems, focusing on structural equilibrium and the construction of force diagrams. It explains how a lattice always maintains static equilibrium, regardless of its shape or applied loads. The instructor demonstrates the process of finding reactions and building force diagrams step by step, emphasizing the importance of considering nodes with unknown intensities. Examples of non-triangular lattice systems, such as the Magazzini Generali in Chiasso and bridges by Robert Maillart and Michel Virlogeux, are also discussed.
