1. Introductory classes
Introduction to structural design:
a) systems with simply or multiple supported spans;
b) systems with structural overhang;
c) the structure of a multi-storey building.

2. Solid mechanics and beam model.
Statically determinate beam systems.
The Cauchy stress.
Introduction to mechanics of materials: steel, wood, reinforced concrete, glass. Characteristics strength and design strength. Basic concepts: elasticity and inelasticity, isotropy and anisotropy, fragility and ductility.
Bernoulli beam model and displacement fields in elastic beams.

3. Between Structural Mechanics and Structural Design.
Loads on structural elements: area of influence of a beam and a pillar.
Preliminary design of beams and a pillars. Stress and displacement analysis of simple beams, design checks. Cantilevers with variable section.
Design of a steel truss in 3D.
Statically indeterminate structures framed resolution methods: integration of the elastic line, force method and stiffness method. Features and benefits of the three methods. Applications of the force method and of the stiffness method. Shear-type frames – Vierendeel beams. Bracing systems: concepts and comparisons. The centre of a system of parallel vectors. The stiffness centre of a braced deck. Grid of beams under bending. Arches: circulars, parabolic. Concept of funicularity. Arch thrust and thrust elimination methods.
